AT a wide range stop valves used in heating networks, there is one element that is used infrequently. It looks like a tee in shape, but internal filling differs greatly from the latter. Yes, and its purpose is completely different. This is a three-way valve for heating with a thermostat. The scheme of its installation, as well as the principle of operation will be considered in today's review.

Three-way valve with thermal head zone type

Basically, three-way valves are divided according to the principle of operation. There are three positions here:

mixing,
separating,
switching.

The former mix two coolant streams with different temperatures into one, the latter, on the contrary, divide one stream into two. And still others simply switch the movement of water from one direction (circuit) to another. The first two varieties appearance they are similar to each other, so a diagram is applied to their case, which shows for what purposes the device should be used.

As for the third position, it is easy to distinguish it from the rest. He additionally has a block with which the switch occurs. A valve of this type is usually installed in a double-circuit when it is necessary to redirect the flow from the heating system to and vice versa.

The device and principle of operation of the three-way valve in the heating system

So, first of all, let's deal with the device. To make it easier to understand what is inside the valve, you need to consider the photo below, in which the device is shown in section. It consists of three nozzles (two lateral one lower), between which there is a mixing chamber. On the fourth side (upper) is thermal headresponsible for controlling the temperature of the coolant.

Inside the device, from the thermostat there is a spring-loaded rod with two flat round valves. Their diameter corresponds to the diameter of the nozzle seats. Instead, one ball valve can be installed, located inside the mixing chamber between two seats. When pressure is applied to the stem, the valves partially block the flow from the lower branch pipe and open the upper one. All the same only happens in reverse if the stem rises.

But here you need to figure out what laws the stock works under, under the influence of what force it lowers or rises. It's all about the thermostat itself. Inside it is a temperature sensor filled with a special liquid. She is heat sensitive. As soon as the temperature of the coolant begins to rise, the liquid expands and rises through the capillary tube into a special bellows (capacity), which is located in the thermal head. The reservoir itself begins to expand, and thus presses on the stock. The latter descends and opens the lower branch pipe, from where it enters the three-way valve cold water. Hot comes from the left pipe (see photo).

Of course, just like that, with any increase in water temperature, pressure cannot occur. To do this, a temperature gradation is set on the thermal head, which is manually adjusted. It is the set parameter that is the moment the rod is pressed.

So, the stem responded to a change in the temperature of the coolant in the supply pipe, opened the lower one for cold water, and inside the valve there was a mixing of hot and cold media until required temperature. That is, it turns out that the temperature of the coolant at the inlet has not changed, but at the outlet it has become less.

In the event that the coolant continues to heat up, the rod may drop to the lowest position. That is, it will completely close the feed hot water and completely open the cold supply. And this will continue until the coolant inside the heating system drops to the required temperature. After that, the top valve will open, it will start up hot water.

This is how a three-way mixing control valve works. As for the separating model, its principle of operation is almost the same, just the other way around. The coolant enters one pipe, inside the device case it is divided into two flows and exits through two adjacent pipes.

This type of valves is installed in those areas where the coolant flow must be divided into two circuits. One of them will be with a constant thermal regime, the other with a variable one. The first is the fluid flow, which is subject to quality requirements. The second with quantity requirements. At the same time, purely constructively, the flow with a constant hydraulic regime is never blocked, because in the design of the device, the stem length is made in such a way that the valve does not close the constant circuit.

But it must be noted that the length of the stem can be adjusted. This makes it possible to adjust the required volume of coolant on a constant circuit. As for the variable, it can completely overlap. This is how the flow and pressure of the coolant in the heating system is regulated. As you can see, the principle of operation of a three-way valve is quite simple. The main thing is to accurately select the type of device and install it in the required place in the circuit.

How does a three-way thermostatic valve work in a "warm floor" system

To make it clear how the valve circuit works, we can give an example of coolant circulation in the underfloor heating system. The three-way valve for underfloor heating is a mixing valve. The circulation scheme here is as follows:

hot water through the collector enters the floor heating system;
it must have a certain temperature, which is monitored precisely in the process of passing through the three-way valve;
as soon as its value exceeds the permissible value, the valve opens one of the circuits, which is connected to the heating return;
cooled coolant enters inside, lowering the temperature,
after which the mixed water enters heating circuit warm floor;
as soon as the temperature drops to the required one, the return circuit is blocked inside the valve by the stem.

Three-way valves with actuators

Experts say that adjusting a three-way valve using a thermal head and a sensor is the simplest and most accurate. In addition, it does not consume electricity. That is why this type of three-way valve is popular today. But the process can be controlled in other ways. The simplest one is manual. Let's face it, this is not the most accurate option, because the range of the stem immersion depth is set by the handle located outside the valve body.

Attention! A valve with such an adjustment is recommended to be used only in those heating systems where the temperature drops of the coolant are insignificant.

The second option is to control the temperature regime with the help of electric drives. They receive commands from the controller.

Motorized 3-way valve

Valve-mounted motors are often referred to as servo motors. In fact, these are ordinary electric motors in which the shaft does not spin, but rotates by a certain degree. It should be noted that this category includes any types of engines, for example, thermal ones. The main thing is to fulfill the condition of rotation, not rotation.

Manufacturers today offer two positions regarding equipment. The first is a complete package that includes a controller and a temperature sensor. It is possible to immediately set the device to the desired temperature, as well as to the angle of rotation, for example, from 0 to 180 °. In this case, any intermediate values are possible. The second is a separate drive with a sensor inside, to which the controller must be added as a separate element.

As for the controller, this is a device that solves the problems of signal management. In the case of heating, it reacts to temperature changes that are signaled to it by a temperature sensor. It processes the signals and decides what to do - open the valve or close it, or rather, turn it clockwise or counterclockwise. Today, manufacturers offer a huge model line of three-way electric valves. One of the most popular brands is ESBE (Sweden).

Three-way valve ESBE with electric actuator

First of all, it must be indicated that this brand of valves has a ball with through slots inside. The latter open or close two channels, the third always remains open. Through it, the coolant enters the heating system. Degree of rotation - 90÷180°.

In stores, the valve of this model is sold separately from the servo drive, therefore, before installation, they are connected to each other by inserting the axis (shaft) of the drive into upper part stock. It has a hole for the axle. After that, it is necessary, exactly according to the instructions attached to the device, to carry out the adjustment in terms of temperature conditions.

Today, the manufacturer offers a fairly wide range of ESBE three-way valves with and without an actuator:

A photo	Model	Purpose
	VTA 200	Designed for systems where there is no water recirculation.
	VTA 270	This is a thermostatic valve for underfloor heating. It is installed if heating is organized in a room with an area of at least 100 m²
	VTA 310	Valve for general use in any heating systems, where the coolant temperature does not exceed +95°C and pressure 0.3 atm.
	VTA 300/ VTA 360	The two models differ from each other only in the direction of water movement in the heating system. They control the temperature well even with pressure surges inside the network.
	VTC300	This is a 3-way valve without servo. It can be installed in systems that use low-power boilers - up to 30 kW.
	DN25	This is a three-way valve for solid fuel boilers. That is, it can withstand coolant temperatures up to + 110 ° C. In this case, the power of the boilers should not be less than 150 kW. This is one of the most unpretentious devices of all present on the market. It can work under any conditions in any heating networks without changing the quality.
	VRG131	This is the most popular and sought-after device that is used in apartments and private houses.

Other models of three-way valves

Another famous brand- Navien three-way valve from a South Korean company. It should be noted that this device is an integral part double-circuit boiler this manufacturer. And it is installed inside the heating equipment. Its main purpose is to separate the coolant for supply to the heating network and for hot water supply.

Attention! Navien valves are beyond repair. The main cause of failure is the gear transmission from the motor to the rod. Parts are not sold anywhere. In case of failure, the device must be replaced with a new one.

Danish company Danfoss - well-known manufacturer three way valves. It offers four models that are designed for different systems:

A photo	Model	Purpose
	VF3	Used in air conditioning and heating systems. Production material - cast iron. With flange connection.
	VMV	It is used only in heating systems. Production material - bronze or stainless steel.
	VRB3	This is a mixer that is used both in heating systems and in refrigeration units. Material - stainless steel.
	VRG3	It is installed in heating networks or when transporting refrigerant. The material is either stainless steel or cast iron.

Schemes for connecting a three-way valve to the heating network

After all the analysis regarding the design of the valve and its principle of operation, an understanding appeared of how it can be used in various heating systems. Most often it is used in three cases.

In system warm floors the coolant temperature must be within +45°C. It is this mode that is supported by the device. This has already been discussed above, and it has been shown how it should work.
To protect against the formation of condensate inside the furnace. This happens when relatively cold water returns to the generator heat exchanger. From this, water droplets from condensed steam form on the outer surfaces. This must not be allowed, because condensate shortens the life of the equipment.
If there is a need to support different temperature regime in different parts of the heating system.

The first option will not be considered, because it has already been described. As for the second case, it is necessary to take the photo below as the basis for the analysis.

There is a double circuit in the diagram: one large one passes through the radiators, the second - a short one through (this is a vertical red line, the beginning of which is at the top to the radiators, the end rests at the bottom of the valve). Until the boiler is warmed up, the coolant moves along a short circuit. The temperature has risen to the required level, the valve closes the bypass and opens the return (lower blue line).

And the third position, which is based on the distribution of the coolant among consumers, in which the required temperature is not always the same. For example, for a boiler indirect heating water with a higher temperature is required, for batteries with a lower one, and even less for underfloor heating.

Attention! In such a scheme, there is no need to install control valves in front of the boiler.

The wiring diagram with the installation of a three-way valve should be approximately the same as shown in the photo below.

Three-way valves for heating with a fixed heating medium temperature

This so-called a budget option. At a price it is cheaper than 30-35% of devices with drives. How is he different from everyone else. In its design there are no rods, no sensors, no thermal heads. The so-called thermostatic element, which is set to certain temperature coolant. For example, it can be either +45°С or +65°С. That is, the indicator can be any, depending on the requirements of the consumer of hot water.

The element is selected at the factory and installed there, so the valve must indicate what outlet temperature will be after it. For example, if you need a valve for underfloor heating, then choose with a temperature of + 45 ° C. positive side of these devices is their cheapness. Negative - the inability to adjust the temperature of the water.

Attention! If this type of valve is installed on the bypass solid fuel boiler, then it is necessary to study the passport of the generator itself before buying. The main indicator for the valve is the temperature of the water in the return circuit. It is for her that the device is selected.

The ESBE three-way valve is just one of the elements of the life support systems of a residential building. On the one hand, this simple design. On the other hand, it performs an important task in engineering networks. Demand creates supply. There are many models on the market by different manufacturers. Three-way valves manufactured under the ESBE brand are distinguished by good performance.

Some useful knowledge

Three way rotary valve ESBE

The three-way valve is a control device in piping systems with a liquid working medium. talking plain language, built into the design of the heating network, it will act as a well-known mixer tap that switches or mixes flows. Installing the valve allows you to solve a number of practical problems:

Redirection of flows coming from different pipelines.
Achieving the desired temperature of the working fluid by mixing hot and cold flow.
Obtaining a jet with a constant temperature by dynamic redirection.

Difficult? Only at first glance. In order to understand the principle of operation of the device, consider its design features.

Design

A three-way mixing valve has a control element, which is a stem or a ball. The rod moves vertically, the ball moves around its axis. Since the movement of the regulating element does not allow to completely block the flow of the working fluid, it is mixed and redistributed. The simplest models are an ordinary crane. Their main advantage is low cost and constructive simplicity. The disadvantage is the impossibility of stabilizing the outlet temperature. Despite the shortcomings, the tap can be installed in underfloor heating systems. Now imagine a motorized valve. This design is already more functional, as it is able to regulate the temperature automatically. A simple valve is a balancing valve. Its main function is to adjust the section for the passage of the work stream. Conventionally, the principle of its operation can be described as follows:

The handle is turned by 50% - uniform mixing of the two streams, since the inlet valves will be equal.
The handle is turned 100% - the first valve is fully pressed and blocks the movement of the fluid flow.

The modifications presented on the market may have different handle turns, but the principle of their operation is preserved. The valve and its position are adjusted manually, thereby ensuring a balance between the two streams.

Kinds

There are several types of such devices:

With hydraulic drive.
With pneumatic drive.
With electric drive.

Motorized three-way valve, e.g. ESBE model, will have a slightly different principle of operation. The electric drive performs the function of a conventional thermostat, which makes it possible not only to mix the flows, but to maintain the set temperature. When the temperature drops / rises, the drive automatically changes the position of the shut-off valves, increasing or decreasing the cross section of the hot water flow. At the same time, the cross section at the cold flow inlet also changes. The result is water with a constant temperature. The ESBE crane does not require any human intervention. Its work is regulated by automation.

Valve principle

Equipped with electric actuators and thermostats, ESBE valves are equally well suited for use in heating and hot water systems. In principle, the valve can be installed in any pipeline where it is necessary to mix two fluid streams with constant maintenance temperature. No matter how high-quality and reliable a three-way valve with a thermostat is, it will have one drawback that is characteristic of absolutely all devices of this type.

Such a disadvantage is the strong narrowing of the entry points. The narrowed section of the entry point, in turn, increases the hydraulic resistance.

Such a faucet will work well in water supply systems. ESBE dampers are suitable for installation in underfloor heating systems, but a special wiring diagram is required. In addition to the designs described above, three-way thermostatic valves. These devices are often confused with each other, but still they are completely different. Thermostatic models have a thermostat with remote sensor, but they differ not only in this element, but also in the principle of operation. Unlike conventional models, in thermostatic taps, the flow is regulated only at one point, the remaining two are open, and their cross section does not change. When choosing such a design, you need to check if there is narrowness at point 2, otherwise the hydraulic resistance will lead to difficulties in the operation of the device. It may be necessary to install a mixing valve in an alternative ring to minimize the problem.

Wiring diagrams

Three-way valve - switching circuit

Almost all three-way valves on the market are connected in the same way. Consider it on the example of ESBE cranes. Let's start with water supply systems, since the mixer tap is used most often here. The main purpose for which the valve is installed is to reduce the risk of backflow. Between the two streams - with cold and hot water - there will inevitably be a pressure drop. It can lead to reverse flow. When installing ESBE valves, such incidents are rare. In heating systems, ESBE valves are used only in three directions:

In mixing units of "warm floor" type systems.
To stabilize the temperature of the liquid flow in the inlet pipeline of the boiler.
To reduce the supply of coolant with high temperature from the boiler to the pipeline.

Valve in the mixing unit

Consider how the ESBE crane is used in underfloor heating systems. The mixing unit creates an additional circuit in the system. It is connected to the distribution manifold by two points, which ensures constant circulation of the liquid at the outlet. At the input, the flow is provided only if it is necessary to receive additional heat. A valve with a thermostat is connected to the mixing unit. Since at point 2 all valves, including the ESBE, are narrowed, insufficient pump flow can be observed. To increase it, a second line is being created, which makes it possible to reduce the consumption of electricity by pumping equipment. The second line is not always required. Some models of three-way valves have sufficient orifice.

Scheme of a warm floor with a three-way valve

In the event that there is insufficient flow power on the first line, the thermostat will not be able to open the passage to the required value . The problem is easily solved in two ways: narrowing the second line or installing a balancing valve on it. The second way is more productive. It allows you to fine-tune the flow. You can connect a three-way valve according to another scheme that does not require the installation of a balancing valve. For this, pumping equipment is connected to the second line. As a result, the temperature of the inlet and outlet streams is compared. A thermostatic valve can be installed in systems with a single circuit. The simplest example of such systems is underfloor heating in small rooms. Creating a mixing node here , with its large size , is not always justified. It is better to connect a warm floor with one circuit. A three-way valve with a thermostat is installed on the return line, through which the already cooled coolant flows. In this case, the thermostat will move the shut-off valves, increasing the cross section and opening the flow. After heating the pipe, the temperature sensor reads the data and reduces the flow.

For heating boilers

Three-way valves for heating boilers should be considered separately. The main task of their installation is to prevent a cold flow of coolant to the incoming pipeline connected to the boiler. Otherwise, condensation will begin to form on the pipes, and temperature changes in the system will lead to its deformation at the joints. There is no need to talk about the consequences of such deformations. At best, a small leak forms, at worst, the system will have to be completely changed.

Three-way valve in the heating system

It is especially important to connect shut-off valves to solid fuel boilers characterized by significant temperature differences during operation. Connecting the mixing valve allows you to ensure that no liquid enters the inlet of the boiler equipment, the temperature of which is below 50 degrees. As a result, the temperature difference decreases negative impact cold with all the ensuing consequences is reduced. It is recommended to install mixing valves in systems with plastic pipeline. Here the goal is to prevent high temperature coolant from entering the pipeline. With all the advantages of polymers, they do not withstand the frequent increase in temperatures above operating parameters. Under such operating conditions, the pipeline is rapidly destroyed. Temperature indicators recommended by experts range from 75 to 85 degrees. The installation of valves solves many problems, but the model must be selected exactly according to the technical characteristics of the utility network, and must have sufficient passage.

Conclusion

The simplest shut-off valve - three-way mixing valves - an important element engineering communications. Modern models, created at the intersection of old traditions and modern technologies, have made it possible to achieve excellent results of their use for a variety of purposes.

A three-way valve in a water supply or heating system is responsible for mixing or separating liquids of different temperatures, as well as for obtaining the required temperature at the outlet of the liquid (adjusting the temperature of the coolant using a servo drive).

Design features

The body of the device contains two inlets and one outlet for liquids and a control element, which can be different design(for example, a rotary ball or a running rod), also a place for a servo.

Usually, the valve is not designed to completely shut off the liquid outlet, but is only capable of controlling the mixing ratio of the liquids and the temperature in the system. The instruction does not imply, but functionally, it is quite possible to shut off the liquid supply.

A three-way valve of some kind, which performs a dividing function, may have a rotary servo drive to redirect the flow to different pipes(Then it is called "shut-off").

In this case, gradual or smooth mixing of liquids with temperature control does not occur, but the rotary mechanism consists of a ball (like a Bugatti ball valve).

There are several varieties of it, according to the type of drive mechanism, performing the same functions:

Hydraulic slewing drive;
Pneumatic drive;
Electric servo.

Yes, three Esbe's new valve, having a servo drive, will assume the actual sample itself and a compatible drive manufactured by the same company.

Types and differences

Esbe has been in business for over a hundred years and specializes in temperature control products for hydraulic systems small buildings.

It manufactures a valve and a rotary actuator for cooling or heating systems, also working "in conjunction" with sensors for internal and outdoor temperature in system. The principle of operation of the Esbe three-way valve is similar to the above options.

The company produces several model series of three-way valves, including a mixing valve:

Rotary valves (series models: VRG130, VRG330, 3F, H, VRH130, HG);
Linear valves (series models: VLF300, VLF200, VLE132);
Thermostatic mixing valve (series models: VTA and VTS).

Rotary valves

Valves of the VRG130 series are applied to systems of hot/cold water supply. This model range, as well as the subsequent ones, there are various options (for example, the three-way valve from Esbe VRG 131 also belongs to this series and has a connection for a servo).

They are compact mixing models made of brass alloys, designed to minimize leakage and with a manual adjustment dial. The instruction indicates that they are also compatible with systems automatic control and Esbe controllers to automate valve operation.

Esbe three-way valve of this model series - available in sizes DN 15-50, pressure class - PN 10, model options include varieties with internal (three-way mixing valve type Esbe model VRG131 with connection for actuator), external thread(model VRG132), with union nut or compression fittings.

three-way Esbe's VRG330 Series Mixing Valve has similar features to the previously described VRG131 Series (DN 20-50, PN 10) but is specifically designed for high flows (60 percent kvs difference between inlets).

It can also be equipped with compatible controllers and automatic control. Available with three connection types: internal thread, external thread, rotating nut.

According to Esbe specification, 3F series rotary mixing valves are designed for heating and cooling applications.

Esbe controllers and automatic control systems can also be used with them.

For ease of installation, the Esbe 3F three-way valve is marked with an adjustment scale on both sides. The valve body is made of cast iron, and the model is also supplied with an adapter for a flange pipe PN 6, model sizes - DN25-150.

The mixing valve from Esbe series H (DN25-40) and HG (DN25) is designed for installation in confined spaces.

This three-way control valve from Esbe is used only for heating systems and is specified for operation with a boiler group (made of cast iron, special "H"-shaped body). It also has an acceptable price.

As the main type of connection, both internal thread and its mixed type are used. Compatible with controllers and Esbe drives like VRG131.

Models of the VRH130 series are also made in the "H"-shaped version, but made of brass with a pressure class of PN 10. This model is more versatile than the previous sample and can also be used in water supply systems, is available with different body widths.

Line valves

The VLF300 series is a 3-way mixing line with sizes DN 15-50.

This model range is It is made of nodular cast iron and can be used with working fluids such as cold/hot water, and which contain antifreeze components (glycol, for example).

In the latter case, the sample must be equipped with a rod heater. It is completed with a flange for a PN 6 pipe. Models similar to those previously indicated, VLF200 dn25, are distinguished by a high working pressure of up to 16 bar (against 6 bar for the previously indicated model range).

Models VLE132 - made of bronze with sizes DN 15-50. These are linear motorized valves, which, like the previously mentioned similar models, can use water with glycol as working fluids (connection - external thread PN16), unlike the VRG131 series. Its price ranges from 140 to 350 euros.

All listed 3-way in-line valves are compatible with the Esbe controller and actuator.

thermostatic mixing valve

VTS520 / 550 - the instruction indicates that the three-way valves are designed to work with hot water systems that are connected to a solar heating system. Its price starts from 150 euros.

A feature of this model range is that the Esbe three-way thermostatic valve comes with specialized protection against burns, since the liquid circulating in the system is of a sufficiently high temperature.

Esbe's three-way thermostatic mixing valve with "scald protection" features a sensor that automatically turns off the hot water servo if cold water is not supplied.

The coolant with which these models work is water (including drinking water), coolant closed systems- this is water with non-freezing components. Pressure class - PN 10, the body is made of brass, resistant to corrosion, for example, the VRG131 valve is not suitable for such a system.

VTA330/530 is Esbe's thermostatic mixing valve of this series designed for use in domestic hot water systems, as well as in faucets or showers where no other means of temperature control is provided (VTA330), or in domestic hot water systems with high flow (VTA530). Its price is around 150 euros.

Also equipped with a security system you from burns. Pressure class PN 10 (material - brass, resistant to corrosion), is available with external threaded connection, fittings or adapters.

VTA360/560 - a series similar to the previous one, but equipped with large quantity fittings and connections. The instruction assumes that the three-way drive Esbe devices This series must also be compatible with the specified company in the specification.

Representatives of the VTA320/520 series can be used both in conditions similar to the operating modes of the previous model ranges, and in systems where other temperature control systems are present.

These valves are recommended for hot water circulation systems (HWC) or underfloor heating systems. Also equipped with "burn protection". VTA370 / 570 - models designed for use in the "warm floor" system, have a high throughput.

VTA310 - sample supplied with adjusting knob, without burn protection system. It is used in domestic water supply systems, including - in the system of hot water supply of a closed cycle (HWC). The price for it starts from 50 euros.

Installation features and prices

When installing a three-way mixing valve, various options, instructions and algorithms are selected for installation. As a rule, the part is not installed directly to the heat source, since the system uses a non-pressure manifold or "hydraulic arrowhead".

In the version for heating, the simplified instruction assumes that the coolant is supplied from the boiler to the valve, from there the coolant is fed into the heating system through the pump.

The liquid that has passed through the heating system and cooled down is sent to the boiler for heating, but also to the mixing valve, which ensures temperature control the supplied substance.

The instruction for the Esbe three-way valve usually involves a description of the connection of the valve to the system, which, depending on the model range, may be different.

The cw602n Esbe three-way valve (brass brand is indicated here) of the VRG130 model range (namely, VRG131 ½) costs an average of $ 170 (if purchased complete with an actuator).

The price of a three-way valve from Esbe linear VLA330, depending on the configuration, is $ 150 (not equipped with an electric actuator).

The Esbe three-way thermostatic valve (VTA 320) can be priced at $70 or more.

Esbe valves are one of the most reliable and functional components used in various water supply systems, including domestic and main ones. It has a very wide range, which includes: rotary vrg131, dn25, as well as other popular varieties.

Currently, a three-way rotary sample of such equipment can be installed in every home. In order to do it right, let's look at the intricacies of working with such equipment and the features of its use.

Esbe valves - technical features of devices

Esbe valves are a variety of devices used to control a liquid or gas when it is supplied from one pipe to another. The three-way type of valves is distinguished by the presence of three connections that allow you to effectively redirect the flows in the system, especially in the case of mixing hot and cold water.

Adjusting the operation of valves of this type within the same system can realize the servo. This device needs a little more attention.

Servo. This is a separate element in the system that controls the position of the valves. A servo drive is usually the most affordable and easy to install, which is why it is most often used for.

By structural features the servo drive can be different, most often they are included in the category of such devices. For example, this can be installed with vrg131 samples. They give today highest quality and accuracy in system maintenance, which is why they are so popular among consumers.

In some devices, a servo drive, as well as motor control is not used. In such cases, such special devices are used as for adjusting the operation of the equipment.

Such varieties include, for example, a dn25 valve, which can be mounted in a crane without a drive.

Esbe products are quite popular today. is no exception. It is one of the many elements that are included in the life support system of residential buildings.

The need to use

This design, on the one hand, is quite simple, but on the other hand, it is designed to perform an extremely important task, being part of engineering networks. Everyone knows the rule that demand creates supply, which is why on the market today you can find many models that are represented by various manufacturers. However, valves produced by Esbe are distinguished by excellent performance. A three-way valve of this type can be purchased at an affordable cost. This is confirmed by user reviews.

Design features

In a wide range today you can find Esbe products. The three-way valve is no exception. This element has a regulating component, which is a ball or a rod. The latter moves vertically, but as for the ball, its movement occurs around its axis. Due to the fact that the movements of the regulating element do not allow to block the flow of liquid, distribution and mixing occurs. The most common and simple models are cranes.

Main plus

Their main advantage is low cost and simplicity. However, if you need to adjust the Esbe three-way valve, then you should exclude the purchase simple devices, since they have the main drawback, expressed in the inability to stabilize the temperature regime at the outlet.

Carrying out installation work

Almost all described valves that are on the market are connected on the basis of one scheme. Most often, mixer taps are used in water supply systems. Their main goal is to reduce the risk of backflow. Between the streams of cold and hot water, a pressure difference will inevitably occur. It can cause reverse flow. If you install a valve, then you will not encounter such a problem. If we are talking about a heating system, then such devices are used exclusively in three directions, namely, to stabilize the temperature regime of the coolant flow in the incoming pipeline of boiler equipment, to reduce the supply of high-temperature water from the heating device to the pipeline, as well as in the conditions of mixing units of systems type of underfloor heating.

Connection in the mixing unit

If you are interested in Esbe products, the three-way valve can be purchased from any relevant store. One has only to consider before that how the tap is used in the underfloor heating system. The use of a mixing unit allows you to create an additional circuit in the system. It connects with two points to this allows for a constant circulation of water at the outlet. As for the inlet, the flow is provided only if there is a need to obtain additional heat. The thermostatic valve is connected to the mixing unit. Due to the fact that all valves are at the point, they are narrowed, which can cause insufficient flow of pumping equipment. To increase it, it is necessary to create an additional line, with which you can reduce the electricity consumption of the pump. During the installation process, it is worth remembering that a second line is not always required. A number of valve models have a fairly large passage. An Esbe three-way valve, whose connection diagram can be designed based on the instructions presented in the article, may suggest insufficient flow capacity in the first line. In this case, the thermostat is not able to open the passage of the required size. This question can be easily solved in two ways: the first involves narrowing the second line, while the other option is to mount on it. The latter option is considered more productive, as it allows you to adjust the flow.

Alternative installation option

Installation of the Esbe three-way valve can also be done by another method. It does not involve the use of a balancing crane. The pump is connected to the second line, eventually the temperature of the outlet and inlet streams equalize. A thermostatic valve is found in single circuit systems. The simplest example of such systems is underfloor heating in small rooms. AT this case it is not always justified to create a mixing unit with large dimensions. It is best to connect the underfloor heating system using one circuit. If you are thinking about how to connect an Esbe three-way valve with an electric drive, then it can be placed on the return line, through which cooled water runs. In this case, the thermostat will lead to the movement of the valves, the cross section will be increased, and the flow will be open. As soon as the pipe is heated, the temperature sensor will detect this and reduce the flow.

Installation of a valve for a heating boiler

This issue, according to professionals, must be considered separately. the main task installation is to exclude the entry of a cold water flow to the incoming pipeline, which is connected to heating equipment. If this requirement is not taken into account, then condensation will occur on the pipes, temperature drops will lead to deformation at the joints. If we talk about the consequences of deformation, then at best you will encounter a small leak, while in worst system will need to be completely changed. In order to avoid the need to repair the Esbe three-way valve, it is important to connect the shut-off valves to the boiler, which is characterized by temperature changes during operation. If you install a mixing valve, then you can ensure that water does not enter the inlet of the equipment, the temperature of which is below 50 degrees. The temperature difference is significantly reduced, the negative impact of cold is reduced. Experts advise supplementing systems that are equipped with plastic pipelines with mixing valves. In this case, the task is to prevent the ingress of high temperature water into the pipeline. While polymers have many advantages, they are not very good at frequent drops temperatures that may be higher than operating.

Under the influence of such conditions, the pipeline system fails soon enough. Experts advise choosing Esbe products. The three-way valve, the installation instructions for which are presented in the article, has been manufactured by this company for a long time. If you use this element, then you can provide temperature readings ranging from 75 to 85 degrees, which are recommended by experts. Mounting the valve allows you to cope with many problems, however, the model must be selected in accordance with the characteristics of the network, and also have a sufficiently large passage.

Adjustment features

When purchasing Esbe products - a three-way valve, the installation and adjustment instructions for which are presented in the article - you must remember that with this device it is possible to mix the cooled water from the return into the supply. For high-quality regulation, not only a three-way valve, but also a four-way valve, which must be present in the heating system, is installed in the system independently. It is located directly in front of the contour of the warm floor. The handle allows you to open the bypass, while the circulation pumps and equipment draw in the cooled coolant from the return, where it is mixed with hot water. In order for the adjustment to be made as efficiently as possible, you should understand what happens at certain positions of the handle. The latter can be set to the bypass overlap position, while the hot coolant will flow into the pipe of the underfloor heating system. As for the mode in which the supply is blocked, water enters the tank and runs in a small circle. The third position allows you to feed the supply from the return system without blocking the full cycle of water passage throughout the circuit.

Conclusion

Specialists in recent times it is increasingly recommended to purchase Esbe brand products. A three-way valve, the instruction, the wiring diagram of which is presented in the article, is just an example of this. It can act as an indispensable element of the heating system and part of the boiler equipment, however, it is important to choose the right model and install it, observing the technology.

Design features

The body of the device contains two inlets and one outlet for liquids and a control element, which can be of different designs (for example, a rotary ball or a travel rod), as well as a place for a servo drive.

A three-way valve of a certain variety, which performs a dividing function, may have a rotary servo to redirect the flow to different pipes (then it is called "shut-off").

In this case, there is no gradual or smooth mixing of liquids with temperature control, and the rotary mechanism itself consists of a ball (like a Bugatti ball valve).

There are several varieties of it, according to the type of drive mechanism, performing the same functions:

Hydraulic slewing drive;
Pneumatic drive;
Electric servo.

Yes, three Esbe's new valve, having a servo drive, will assume the actual sample itself and a compatible drive manufactured by the same company.

Types and differences

Esbe has been in business for over a hundred years and specializes in temperature control for hydraulic systems in small buildings.

It manufactures a valve and a rotary actuator for cooling or heating systems, also working "in conjunction" with indoor and outdoor temperature sensors in the system. The principle of operation of the Esbe three-way valve is similar to the above options.

The company produces several model series of three-way valves, including a mixing valve:

Rotary valves (series models: VRG130, VRG330, 3F, H, VRH130, HG);
Linear valves (series models: VLF300, VLF200, VLE132);
Thermostatic mixing valve (series models: VTA and VTS).

Rotary valves

Valves of the VRG130 series are applied to systems of hot/cold water supply. This model range, as well as the subsequent ones, has various options (for example, the three-way valve from Esbe VRG 131 also belongs to this series and has a connection for a servo drive).

They are compact mixing models made of brass alloys, designed to minimize leakage and with a manual adjustment dial. The instruction indicates that they are also compatible with Esbe automatic control systems and controllers, which allow automating the operation of valves.

(model VRG132), with union nut or compression fittings.

It can also be equipped with compatible controllers and automatic control. Available with three types of connection: internal thread, external thread, rotating nut.

According to Esbe specification, 3F series rotary mixing valves are designed for heating and cooling applications.

Esbe controllers and automatic control systems can also be used with them.

For ease of installation, the Esbe 3F three-way valve is marked with an adjustment scale on both sides. The valve body is made of cast iron, the model is also supplied with an adapter for a flange pipe PN 6, model sizes - DN25-150.

The mixing valve from Esbe series H (DN25-40) and HG (DN25) is designed for installation in confined spaces.

As the main type of connection, both internal thread and its mixed type are used. Compatible with Esbe controllers and actuators like VRG131 .

Line valves

The VLF300 series is a 3-way mixing line with sizes DN 15-50.

This model range is It is made of nodular cast iron and can be used with working fluids such as cold/hot water, and which contain antifreeze components (glycol, for example).

All listed 3-way in-line valves are compatible with the Esbe controller and actuator.

thermostatic mixing valve

VTS520 / 550 - the instruction indicates that the three-way valves are designed to work with hot water systems that are connected to a solar heating system. Its price starts from 150 euros.

Esbe's three-way thermostatic mixing valve with "scald protection" features a sensor that automatically turns off the hot water servo if cold water is not supplied.

The coolant with which these models work is water (including drinking water), the coolant of closed systems is water with non-freezing components. Pressure class - PN 10, the body is made of brass, resistant to corrosion, for example, the VRG131 valve is not suitable for such a system.

Also equipped with a security system you from burns. Pressure class PN 10 (material - brass, resistant to corrosion), is available with external threaded connection, fittings or adapters.

VTA360/560 - a series similar to the previous one, but equipped with a large number of fittings and connections. The instruction assumes that the drive of the Esbe three-way device of this series must also be compatible with those specified by the company in the specification.

Valve design overview (video)

Installation features and prices

In the version for heating, the simplified instruction assumes that the coolant is supplied from the boiler to the valve, from there the coolant is fed into the heating system through the pump.

The liquid that has passed through the heating system and cooled down is sent to the boiler for heating, but also to the mixing valve, which ensures the temperature control of the supplied substance.

The instruction for the Esbe three-way valve usually involves a description of the connection of the valve to the system, which, depending on the model range, may be different.

The cw602n Esbe three-way valve (brass brand is indicated here) of the VRG130 model range (namely, VRG131 ½) costs an average of $ 170 (if purchased complete with an actuator).

The price of a three-way valve from Esbe linear VLA330, depending on the configuration, is $ 150 (not equipped with an electric actuator).

The Esbe three-way thermostatic valve (VTA 320) can be priced at $70 or more.

Despite the simple design, the esbe three-way valve is one of those elements on which the life support of the whole house directly depends. Devices of this type are commercially available in several varieties.

general information

A three-way valve is a device for adjusting pipeline networks with liquid working medium. If you explain popularly, after being included in the heating system, the device will perform the function of a well-known mixer tap, the task of which is to switch or mix flows.

Thanks to the esbe three-way valve, the following results are achieved:

Redirecting streams from different networks.
The working fluid is brought to the required temperature indicator by mixing cold and hot liquids.
Dynamic redirection makes it possible to obtain a jet of stable temperature.

Design features of the ESBE three-way valve

The adjustment of the three-way valve is carried out using a stem or ball. In the first case, the adjusting element moves in the vertical direction, in the second - around its axis. This element moves in such a way that a complete blockage of the flow of the working fluid does not occur: it only mixes and redirects. The simplest example of such a device is a conventional crane. His forte– simple design and low cost; weak - the impossibility of obtaining a stable outlet temperature. For all their shortcomings, taps are widely used in underfloor heating systems.

If an electric drive is introduced into the design of a conventional valve, then it will be possible to significantly increase its functionality: the device will be able to regulate the temperature of the liquid medium in automatic mode. The task of simple balancing valves is to adjust the section for the flow of the working flow.

The device works like this:

When the handle is turned halfway, the two flows are evenly mixed, which is ensured by the equality of the inlet valves.
If the handle is turned all the way, the first valve will be pressed, due to which the liquid flow is completely blocked.

For commercially available models, the turns of the handles may differ slightly, which in no way affects the principle of operation of the devices.

Main varieties

Three-way valves are of three types:

Hydraulic.
Electric.
Pneumatic.

Motorized appliances (eg model ESBE) differ slightly in their principle of operation. An electric appendage acts here like a conventional thermostat: thanks to it, the flows are not only mixed, but also kept at the desired temperature. During a decrease or increase in temperature, the position of the shut-off valves is automatically changed. As a result, the flow cross section increases or decreases. In parallel, there is a change in the cross section at the inlet of the cold flow, which makes it possible to inform the water at the outlet of a stable temperature. Wherein three-way esbe the valve completely dispenses with human control: the equipment is controlled by automation.

The ESBE valve with electric actuator and thermostat can be successfully used in heating systems and in hot water supply. Strictly speaking, such a valve can be equipped with any type of pipeline, where it is required to mix two liquid streams and maintain a stable temperature. Even the highest quality and most reliable models of a three-way valve with a thermostat have one common drawback for products of this type: the entry points through which fluid enters are very narrowed. As a result, it stimulates the growth hydraulic resistance.

These faucets are great for plumbing. ESBE valves are often equipped with underfloor heating, although they use a special connection scheme. Along with the modifications mentioned above, three-way thermostatic valves can be found on sale. Despite the apparent similarity of these devices, their functions differ in many ways. In thermostatic varieties, thermostats with a remote type sensor are used. In addition, the principle of operation here is also different.

Unlike standard models, thermostatic taps control the flow at only one point. The other two inputs are in a permanently open position, with a stable section. When purchasing such a design, it is important to test the second point for narrowness, otherwise the device may experience difficulties due to high hydraulic resistance. If such a defect is found, the problem can be solved by installing a mixing valve in an additional circuit.

ESBE tap connection principle

For the vast majority of commercially available three-way devices, one connection scheme is used. For example, consider installing an esbe three-way valve. Better start with plumbing system where mixing taps are most common. Valves in this case prevent the formation of backflow. The fact is that cold and hot flows have different pressure which causes fluctuations. As a result, reverse flow may occur. Systems with ESBE valves are completely safe in this respect.

In heating systems, only three sections can be equipped with devices of this type:

Mixers of the "warm floor" system.
The pipe entering the boiler. Thus, stabilization of the temperature of the coolant in the incoming pipeline is achieved.
Outlet pipe, to reduce the supply of heated coolant.

mixing unit

The use of the esbe valve for underfloor heating has its own specifics. The location of the mixing unit is an additional circuit. Switching with the manifold is carried out through two points: this allows the inlet coolant to constantly circulate. The inlet flow is opened only when there is a need for additional heat.

The mixing unit is commutated with a valve and a thermostat. You need to understand that a thermostat for a water-heated floor allows you to reduce heating costs. Given the narrowness of all valves at point 2, the pump may be faced with the problem of insufficient flow. To solve the problem, it is necessary to live the second line, which reduces the level of electricity consumption. But such a need does not always arise, because. the cross section of some three-way valves is quite large.

In a situation where the first line has insufficient flow capacity, the thermostat does not block the passage on the required scale.

To get out of this situation, two options are usually used:

The second line is narrowing.
The balancing valve is installed.

The second method is considered more effective, because. the flow in this case is tuned more precisely. There is another scheme for connecting the esbe three-way valve for underfloor heating - switching the pump to the second line: here balancing crane not needed. This allows you to equalize the temperature regime in the inlet and outlet streams.

Installation of a valve with a thermostat can be carried out in single-circuit systems. Their simplest variation is underfloor heating. small area. In this case, use the overall mixing unit not very practical. A more appropriate solution would be to connect a single-circuit underfloor heating. The installation of a three-way valve with a thermostat is carried out on a return pipe containing a cooled coolant. Thanks to the thermostat, the shut-off valve is activated, which increases the cross section. When the pipe heats up, the temperature sensor detects this and reduces the flow.

Application of valves for heating boilers

Three-way valves for heating boilers deserve special attention. They perform the task of preventing the cooled coolant from getting inside the pipeline entering the boiler. If this is not done, the pipes will begin to become covered with condensate, and a dangerous temperature difference will occur in the system. This is fraught with deformations of the docking sections, the most harmless consequence of which will be the appearance of small leaks. If you do not respond in time, the system may completely fail.

With particular responsibility, one should take the installation of shut-off valves in the piping of a solid fuel boiler, during which significant temperature differences occur (read also: ""). The mixing valve allows you to protect boiler equipment from the ingress of a coolant with a temperature below +50 degrees. In this way, a reduction in the temperature difference is achieved, which has a positive effect on the efficiency and durability of the system.

Experts recommend using mixing valves also in systems with plastic piping. Although polymer communications have a number of advantages, however, the frequent excess of operating temperature parameters affects them destructively. According to the standards, the most comfortable temperature regime is in the range of + 75-85 degrees. Valves protect plastic pipes from many negative consequences. The selection of a device model must be taken responsibly, taking into account specifications engineering network.
