We choose an esbe three-way valve for heating and underfloor heating - types of esbe taps, characteristics. Model overview of Esbe three-way mixing valves esbe mixing valve types of installation

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

AT 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 streams of cold and hot water inevitably there will be a pressure drop. 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 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 Esbe valve, the connection diagram of which 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 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 creation is not always justified mixing unit with large dimensions. It is best to connect the underfloor heating system using one circuit. If you are wondering how to connect three-way valve Esbe with an electric drive, then it can be placed on the return line, through which the 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 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 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 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. 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 the liquid is supplied. High Quality and in specified quantities. 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.

According to the 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 temperature regime rooms, and the working fluid will flow in accordance with the remoteness 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. Armature 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 throughput 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 an American Honeywell - a true brainchild of 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. Note also that this scheme installation provides for the possible termination of the circulation of liquid through the source, if the installation was carried out without 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.

Video - Three-way valve and its principle of operation

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

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.

A motorized three-way valve, such as the ESBE model, will have a slightly different operating principle. 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.

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 a narrowness at point 2, otherwise hydraulic resistance lead to problems with the operation of the device. It may be necessary to install a mixing valve in an alternative ring to minimize the problem.

Wiring diagrams

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 high temperature coolant 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 at two points, which ensures constant circulation of the liquid at the outlet. At the inlet, the flow is provided only if additional heat is needed. A valve with a thermostat is connected to the mixing unit. Since at point 2 all valves, including the ESBE, are narrowed, there may be insufficient pump flow. 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.

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: by narrowing the second line or by installing balancing valve. 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 pump equipment 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 spaces. 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.

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, the negative impact of cold with all the ensuing consequences is reduced. The installation of mixing valves in systems with plastic piping is recommended. 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 technical specifications engineering network, and must have sufficient passage.

Conclusion

Protozoa shut-off valves– 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.
