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. The servo drive is usually the most affordable and easy to install, which is why it is most often used for.

According to the design features, the servo drive can be different, most often the category of such devices includes. For example, this can be installed with vrg131 samples. Today they provide the 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.

Flanged mixing valves Esbe 3F, 4F ESBE 3F, 4F flanged mixing valves 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 free of 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. Flange connections, body - cast iron, spool - brass, seal - EPDM, T=-10C...110C. Pmax=6 bar

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 common house controller, which, based on the readings of various temperature sensors, 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.

I provide passport data and a video of the operation of the servo. I also show how to connect and mount and then set up a servomotor for a three-way valve.
And so let's get started...
In this article, we will look at the most versatile servo actuator ESBE 99K2, which is shown in the picture, and the ESBE VRG131 valve.
The servomotor is sold with two connection kits, for two different standards of three-way valves with a rotating valve in a circular direction for unlimited rotation. More details will be indicated both in the passport and on the video.
It's important to understand:
1. The three-way valve itself - has a ball valve that rotates in a circular direction for unlimited rotation. For work, the valve must be turned clockwise, and counterclockwise from 90-180 degrees of rotation.
2. Servo is the electrical equipment and device to rotate this ball valve. Rotation of the valve opens and closes two passages, and the third passage is constantly open. The servomotor, by means of a temperature sensor, drives the rotation in the desired direction to open or close the supply hot circulation line. More details on the video and in the passport. We also analyze how to set up a valve for a specific circuit.
ESBE 99K2 servo drive, advantages:

• Power supply 220 Volt
• Electric remote temperature sensor
• Temperature control(15-70 degrees) in real time
• Adjusting the time (1-70 seconds) for checking the temperature sensor and turning on the turn.
• Rotation adjustment: from 10-180 degrees
• Switching rotation clockwise and counterclockwise (reverse)

At 90 degrees, it is possible in real time to set the required rotation of the ball valve for testing (press the button and scroll). If a 180 degree turn is required, the knob is not installed and adjustment cannot be made. Yes, and this is nothing, the function is useful only for masters when testing the mixing unit.
Flaw: If there is no electricity, the valve does not return to any position, but freezes in the position in which it is set automatically.
But in general it is used for large facilities where it is necessary to make a mixing unit with a high flow rate (from 2 cubic meters per hour and more).

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 Esbe three-way valve, then you should exclude the purchase of simple devices, since they have the main drawback, expressed in the inability to stabilize the outlet temperature.

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 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 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 issue 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 flows 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 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 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 of the installation is to prevent the entry of a cold water flow to the incoming pipeline, which is connected to the 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 at worst the 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 do not cope well with frequent temperature changes, which can be higher than operating temperatures.

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 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

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.

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 is a simple design. On the other hand, it performs an important task in engineering networks. Demand creates supply. There are many models on the market from different manufacturers. Three-way valves manufactured under the ESBE brand are distinguished by good performance.

Some useful knowledge

Three-way butterfly valve ESBE

The three-way valve is a control device in piping systems with a liquid working medium. In simple terms, built into the design of the heating network, it will act like 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.

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 liquid streams with constant temperature maintenance. 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 are on the market. These devices are often confused with each other, but still they are completely different. Thermostatic models have a thermostat with a 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 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 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.

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 coolant flow 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 shutoff valves to solid fuel boilers, which are characterized by significant temperature differences during operation. Connecting a mixing valve makes it possible to ensure that liquid with a temperature below 50 degrees does not enter the boiler equipment. As a result, the temperature difference decreases, the negative impact of cold with all the ensuing consequences is reduced. It is recommended to install mixing valves in systems with plastic piping. 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 valves - three-way mixing valves - are an important element of 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.
