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.

Valve adjustment of this typewithin the same system can realize the servo. This device needs a little more attention.



Servo. it separate element in the system that controls the position of the valves. The 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 the category of such devices includes. 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.

  • model vrg131 - designed specifically for use in hot water networks. Released vrg from a specialized brass alloy, which significantly increases its service life. Can be set manually. It is recommended to use a servomotor from the same manufacturer to control this three-way valve.

Esbe products are quite popular today. is no exception. It is one of the many elements that are included in 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 manufactured 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 three-way Esbe valve, then it is worth excluding the acquisition simple devices, since they have the main drawback, expressed in the absence of the ability to stabilize temperature regime at the exit.

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 water supply from high temperature from the heating device to the pipeline, as well as in the conditions of mixing units of systems such as 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. Application 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 input, the flow is provided only if there is a need to receive 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. Three-way valve Esbe, whose connection scheme can be developed based on the instructions presented in the article, may suggest insufficient flow capacity on 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. In this case, it is not always justified to create 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 thermal 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 stop valves to the boiler, which is characterized by temperature fluctuations 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 negative impact cold is reduced. Experts advise supplementing systems that are equipped using plastic pipelines, 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 indicators 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 is installed in the system, but also a four-way valve, which must be present in the heating system. It is located directly in front of the contour of the warm floor. The handle allows you to open the bypass, while 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

Recently, experts have increasingly recommended purchasing 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. He can perform indispensable element heating systems and part of the boiler equipment, however, it is important to choose the right model and install it, observing the technology.

In a wide range of valves used for heating systems, there is an element that is used quite rarely. Its shape resembles a tee, although the functions it performs are completely different. We are talking about a three-way valve, the principle of operation of which will be discussed in this article.

The principle of operation of the three-way valve

What is this device, why is it needed at all?

How it works

The three-way valve is mounted on those sections of the pipelines where it is required to divide the flow of the circulating fluid into 2 circuits:

  • with variable hydraulic regime;
  • with constant.

In most cases, a constant flow is required for those for whom a liquid of high quality and in the indicated volumes is supplied. It is regulated in accordance with the quality indicators. As for the variable flow, it is used for objects where quality indicators are not the main ones. There great importance has a quantity factor. Simply put, the supply of coolant there is carried out according to the required amount.

Note! The shut-off valves also include an analogue of the device described in the article - a two-way valve. How is it different? The fact is that the three-way option works on a completely different principle. The rod included in its design is unable to block the flow of fluid, which has constant hydraulic performance.

The stem is open all the time, it is adjusted to one or another volume of liquid. Consequently, users will be able to get the volume they need, both in terms of quantity and quality. In general, this device is unable to stop the supply of liquid to a network in which the hydraulic flow is constant. At the same time, it may well block the flow of a variable type, due to which, in fact, it becomes possible to adjust the flow / pressure.

And if you connect a pair of two-way type devices, you can get one, but three-way. But it is necessary that both work on the reverse, in other words, when one valve is closed, the next one should open.

Valve classification

Without lengthy introductions, we note that the device can be of two types according to the principle of operation. It can be:

  • separating;
  • mixing.

Features of the action of each type are already clear from their name. The mixing device consists of two outlets and an inlet. In other words, it is necessary for mixing fluid flows, which may be required in order to reduce its temperature. By the way, this is the most best option in order to ask desired mode in the "warm floor".

The procedure for adjusting the temperature regime is extremely simple. You just need to know about the current temperature indicators of the incoming fluid flows, accurately calculate the required proportions of each of them so that you get the desired indicators at the output. By the way, this device, subject to proper installation and adjustment, can also function for flow separation.

But the dividing valve divides one flow in two, therefore, it is equipped with one inlet and two outlets. This device is mainly used to separate the flow of hot water into DHW systems. Although quite often it is also found in the piping of air heaters.

Outwardly, both options are almost identical. But if you look at their drawing in section, then their main difference is immediately visible. The stem, which is installed in the mixing type device, has one ball valve. It is located in the center and blocks the main passage.

As for separating devices, in them the stem has two such valves, which are installed at the outlets. They function according to the following principle: one of them is pressed against the saddle, closing the passage, and the other simultaneously opens passage No. 2.

By management method modern models can be:

  • electric;
  • manual.

In most cases, a hand-held device is used, which looks like an ordinary ball valve, but is equipped with three outlet pipes. But electrical models, having automatic control, are used mainly in private houses, namely in order to distribute heat. For example, the user can set the temperature regime by room, and the working fluid will flow in accordance with the distance of the room from heater. As an option - you can combine it with a "warm floor".

Video - Device in the boiler group

Three-way valves, as well as other devices, are defined according to the system pressure and inlet diameter. All this is regulated by GOST. And if the requirements of the latter are not met, it will be regarded as gross violation, especially when it comes to the pressure indicator in the line.

Applications

The three-way valve, the principle of operation of which was discussed above, has a fairly wide scope. So, its varieties, such as an electromagnetic device or a device with a thermal head, are often found in modern highways, where it is necessary to adjust the proportions when mixing two separated liquid flows, but without reducing power or volume.

As for domestic use, the most popular here is a thermostatic mixing device, with which, as noted above, you can adjust the temperature of the working fluid. This liquid can be supplied both to the "warm floor" pipeline and to heating radiators. And if the valve also has automatic control, then it will be possible to control the temperature in the home without any problems!

Note! The use of a three-way valve in a heating system in order to balance temperature fluctuations is extremely beneficial not only in terms of comfort and convenience, but also in terms of cost savings.

The fact is that by regulating the temperature of the liquid on the "return" of the heater, it is possible to significantly reduce the amount of fuel consumed, and this will have a positive effect on the efficiency of the system itself. In some systems, a valve is simply necessary. For example, in a "warm floor" system, this device prevents overheating floor covering above a given level of comfort, thereby relieving users of discomfort.

Control devices of this kind are also used in water supply systems in order to obtain a permanent flow at the required temperature. The simplest example is an ordinary faucet, where you can make water hot/cooler by opening/closing a cold faucet.

Adjusting the flow of the working fluid. What to look for when buying?

Manual adjustment is made using the usual ball valve. Visually, it is very similar to a simple valve, but has an additional outlet. Reinforcement of this kind is used for forced manual control.

As for automatic adjustment, then a special three-way valve is used here, equipped with an electromechanical device for changing the position of the stem. It should be connected to a thermostat in order to be able to adjust the temperature in the room.

Remember that when buying a valve, you must without fail taking into account technical specifications device, which includes the following.

  • Diameter of connection to the heating main. Often this indicator varies from 2 to 4 centimeters, although much depends on the characteristics of the system itself. If the device suitable diameter could not be found, you will have to use special adapters.
  • The possibility of installing a servo drive on a three-way valve, the principle of operation is considered at the beginning of the article. Thanks to this, the device will be able to work automatically. This moment is very important if the device is selected for operation in " warm floors» water type.
  • Finally, this is the throughput of the pipeline. This concept refers to the volume of liquid that can pass through it in a certain time.

Popular manufacturers

There are many manufacturers of three-way valves on the domestic market. The choice of a particular model depends primarily on:

  • type of mechanism (and, we recall, it can be mechanical or electrical);
  • areas of use (DHW, cold water, "warm floor", heating).

The most popular device is considered to be Esbe is a Swedish valve from a company that has been around for over a hundred years. This is a reliable, high-quality and durable product that has proven itself in many areas. Combination European quality and modern technologies.

Another popular model is the American Honeywell - a true brainchild high technology. Simple operation, convenience and comfort, compactness and reliability - that's distinctive features these valves.

Finally, relatively "young", but promising devices are valves of the Valtec line - the result of a joint collaboration between Italian and Russian engineers. All products are of high quality, sold with a warranty period of seven years. They differ in that they have a very affordable price.

How to install a mixing valve with your own hands

This installation scheme is used mainly in boiler rooms. heating systems, which are connected to a hydraulic separator or to a non-pressure manifold. And the pump located in circuit No. 2 provides the required circulation of the working fluid.

Note! If the three-way valve will be connected directly to a bypass heat source connected to port B, then a valve with a hydraulic resistance equal to the same resistance of this source will also be required.

If this is not done, then the consumption of the working fluid for segment A-B will oscillate according to the movement of the stem. We also note that this installation scheme provides for the possible termination of the circulation of liquid through the source, if the installation was carried out without a circulation pump or a hydraulic separator in the main circuit.

It is undesirable to connect the valve to heating networks or a pressure manifold in the absence of devices that throttle excessive pressure. Otherwise, the fluid flow section A-B will fluctuate, and significantly.

If overheating of the return is allowed, excessive pressure is eliminated by means of a jumper installed in parallel to the valve admixture in the circuit.

How to install a dividing valve with your own hands

Providing quantitative adjustment by changing the flow of fluid is the main function that such a three-way valve performs. The principle of its operation is extremely simple and has been discussed above. It is used where it is possible to bypass the liquid to the "return", and the termination of circulation, on the contrary, is not allowed.

Note! This connection scheme has gained wide popularity in water and air heating units that are connected from individual boiler houses.

In order to link the hydraulic circuits, it is necessary that the pressure loss of the consumer be equal to the loss on the balancing valve in the bypass. The diagram shown here is intended for installation on those pipelines in which there is excessive pressure. The liquid in this case moves due to the strong pressure generated by the circulation pump.

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

Recently, experts have increasingly recommended purchasing 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.

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 100 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, like the subsequent ones, has various options(for example, a 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 systems automatic control and Esbe controllers to automate valve operation.

The Esbe three-way valve of this model series is supplied with sizes DN 15-50, pressure class - PN 10, model options include varieties with internal (three-way mixing valve type Esbe models VRG131 with drive connection), 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, 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 Esbe controllers and actuators 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 - have 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 the system solar heating. 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), 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.

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 within 150 euros.

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

VTA360 / 560 - a series similar to the previous one in execution, but equipped with a large number of 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 supplied to 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.

The Swedish company ESBE (Esby) has been a recognized leader in the field of water heating and cooling control systems for many years. ESBE VRG 131 and 3F three-way mixing valves and ESBE ARA and 90 series electric actuators are an example of excellent quality and reliability at an affordable price. A wide range of mixing valves Esbe allows you to do optimal choice depending on system requirements. High quality brass alloys or cast iron are used as materials. The valves are available with threaded or flanged connections.

Flanged mixing valves Esbe 3F, 4F

mixing flanged valves ESBE 3F, 4F are made of cast iron and are widely used in heating and cooling systems. Esbe 3F valves can be used in closed systems with water containing no dissolved oxygen. When the Esbe 3F, 4F valve is operating, the hotter coolant is mixed with the cold one entering the boiler, which ensures an increase in the temperature of the coolant returning to the boiler. This reduces the risk of low temperature corrosion. The valves are manufactured in sizes DN 32-150.

Electric actuators for ESBE poppet control valves

Linear series ESBE drives in 230 V or 24 V version, with analog or pulse control. The actuators have different forces and are adapted to valves with different strokes. A separate line of actuators with a return spring is also presented. Depending on the model, valves equipped with such actuators can be normally closed or normally open.

Three way mixing valve has a fairly simple device. It consists of a housing with two inlets and one outlet, as well as a specially shaped stem, on which a handle (for manual control) or an electric drive (for automatic flow temperature control) is installed. The rod is able to rotate along the vertical axis, blocking to some extent the inlet of hot or cold water, due to which a certain ratio of flows is created and, as a result, a mixture of a given temperature is obtained at the outlet. The body material of a three-way valve is most often brass alloy or cast iron. The stem is made of brass, cast iron or stainless steel.

Three way valve control is carried out with the help of an electric drive installed on the rod, which is supplied separately. The main characteristics of electric actuators are: the time of rotation of the rod by 90 degrees; the force with which the actuator is able to rotate the stem; electrical voltage and control signal (two-point, three-point, proportional). The electric drive receives a signal from the general house controller, which, based on the readings various sensors temperature, calculates the position of the three-way valve stem to obtain the desired temperature of the coolant at the outlet.

Selecting an actuator for a rotary three-way mixing valve. For sleeve mixing valves ESBE actuators of the ARA600 series are used, for flanged cast iron valves the ESBE 90 series is used. If as a mixer, then 3-point control or proportional control is necessary: ​​0-10V signal. Next, select the desired combination of stem rotation time and valve assignment. 60 seconds will be enough for domestic hot water supply, and for supplying coolant to radiators, most often, electric drives with a stem rotation time of 120 seconds are used. If it is necessary to control external equipment depending on the position of the valve (for example, turn off an unnecessary pump, etc.), we determine whether an auxiliary switch is needed. When all the technical characteristics of the electric drive are determined, it will not be difficult to choose from the presented models exactly the one that will perform all the specified functions.
