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.

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 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. 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 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 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 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 do 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, 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

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 of different designs (for example, a rotary ball or a travel rod), as well as a place for a servo drive.

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 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 fluids 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 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, 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.

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 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 flanged 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, 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), 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), 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.

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 arrow".

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 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 (here the brand of brass is indicated) 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.

Three-way mixing valves (taps, valves) and actuators ESBE

Esbe three-way valves are typically used as mixing valves, but can also be used as diverting or separating valves. It must be ensured that the nominal pressure, differential pressure and leakage rate are within acceptable limits. This information is given for each valve.
Four-way valves are usually used when a high return temperature is required (usually for solid fuel boilers). In systems with two heat sources or a storage tank, the valves will help prioritize the use of an inexpensive heat source while maintaining good temperature separation in the storage tank.
The principle of operation of Esbe 3-way valves VRG130. The required temperature in the system is achieved by adding the necessary amounts of water coming from the return pipe supplied to the boiler.

How does an Esbe three-way valve work?

The required temperature in the heating system is ensured by the proportional addition of a colder heat carrier to a hotter heat carrier flow from the boiler.

How does a four way valve work?

Valves of this type have a double mixing function, i.e. the hotter heat carrier is mixed with the colder fluid supplied to the boiler. This allows you to raise the temperature of the coolant in the return (returning to the boiler) and reduce the risk of low-temperature corrosion, which significantly extends the life of the boiler.

How Esbe 3, 4, 5-way and bivalent mixing valves work

Advantages of Esbe mixing valves:

Ease of installation of drives.
The compact size, ease and convenience of installation - at installation the minimum of tools is required.
The minimum dimensions of the mixing valves, facilitating installation in cramped conditions.
Reliable installation of the valve with an internal thread. The edges for the key are wider and have two edges instead of six. This provides a better grip and less risk of slipping the pipe wrench or box wrench.
More flexible cabling. The actuators are supplied complete with a connecting cable, as well as with an additional cable contact. The advantage is that a separate cable can be routed, for example, directly to the circulation pump without being connected via a central controller.
High control precision.
Minimum delay and high accuracy of the entire cycle, from full closing to full opening of the valve, the valves provide the ability to use the full angle of rotation. This adjustment is as close to ideal as possible and provides increased comfort and reduced energy consumption.
Esbe valves are known for their minimal internal leakage and have been awarded "Best Plumbing Product of the Year 2003".
The percentage of leaks is reduced from 0.1 to 0.05%. And this is achieved with double pressure, i.e. at 100 kPa (1.0 bar). A valve that provides tighter shutoff is difficult to find and buy in the rotary valve market.
Easy and convenient regulation, high performance
Reliable and have a long service life

What is kvs? Each mixing valve has a Kvs characteristic (capacity m3/h at a pressure loss of 1 bar). The Kvs parameter helps you determine which valve is right for your heating system. You can determine the Kvs of an Esbe valve using the graph below.

Esbe mixing valve size selection

Selection of Esbe mixing valves of the VRG and VRB series for underfloor or radiator heating systems.
We start from the thermal power of the boiler in kW (for example, 25 kW). We move vertically to the selected temperature regime t (for example, 15 ° C). Then we move horizontally to the shaded area (pressure drop range 3-15 kPa) and choose a lower value of the Kvs coefficient (for example, 4.0).
In this case, we select the desired type of valve with a coefficient Kvs = 4.0

Kvs value is accepted for flow in one direction only
For 4-way valves, double the differential pressure P indicated on the graph is valid.

The materials used, the requirements for the coolant.

Valves in the VRG, VRB and 5MG series are made from a special brass alloy (DZR Dezincification Resistant Brass, CW 602N), which offers advantages that cannot be achieved in designs combining cast iron and brass. This allows them to be used for domestic hot water systems.
Selective corrosion of brass(zinc is released from ordinary brass, leaving a brittle, porous copper mass) is the most dangerous type of corrosion, leading to a rapid decrease in service life and functionality. Coating the inner surface of valves and valves with a layer DZR reduces the chance of dirt and sediment sticking to valves, resulting in reduced wear and cleaner water. The alloy also contains less lead than many other products. and is particularly suitable for the installation of cold water plumbing systems.
All other ESBE valves can only be used in closed systems with water free of dissolved oxygen.
For freeze protection, a heat transfer fluid containing glycol and dissolved oxygen neutralizing additives up to a maximum concentration of 50% may be used. When glycol is added to water, its viscosity increases and its heat capacity changes, so this must be taken into account when choosing a valve. If the percentage of glycol is 30-50%, then another valve with one level higher Kv must be selected. The lower glycol content does not affect valve operation.

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.

Design features

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 fluids 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 100 years and specializes in temperature control for hydraulic systems in small buildings.

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

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, 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.

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.

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.

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 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 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 (here the brand of brass is indicated) 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.
