Three-way valve with electric actuator: types and functions

Today it is impossible to imagine a heating system without balancing, shutoff and control valves. At the same time, thermostatic valves are control valves that perform 2 functions: they provide a comfortable temperature in the room and also monitor energy savings. It should be noted that a three-way control valve with an electric drive can be installed on a single radiator, as well as on an entire branch that supplies the coolant to various heating devices. With the help of such fittings, it is possible to achieve comfortable air temperatures in the room, as well as set the day and night modes. When the temperature drops below a certain temperature, the coolant begins to circulate in the radiator, which leads to energy savings of thirty percent.

Three Way Valve Groups

All valves designed for two-pipe systems are divided into 2 groups - without preliminary and with preliminary settings. Obviously, a three-way thermostatic valve without pre-setting ensures that basically all the radiators in the riser will have an equal flow rate. At the same time, it should be installed primarily depending on the heat loss of the room, which must be compensated. Therefore, it is more profitable to economically use a three-way valve with electric presetting.

It should be borne in mind that the adjustment with their help is very easy, because the values ​​located on the valve head can easily control and set the required temperature.

There is also an alternative configuration option using a valve located at the radiator outlet, although this method is a bit more complicated. Since for starters it is required to completely close it, and then open it to the required number of revolutions, it is obvious that in this case it is quite problematic to carry out control. Consequently, many of these valves do not adjust, which leads to excessive flow of coolant.

Choose a three-way valve with an electric actuator

Recently, the market provides a wide range of control valves, but we must not forget that not all equipment is of excellent quality. Thus, a three-way valve with an electric actuator Danfoss is designed to provide remote flow distribution between all consumers with the highest degree of efficiency. The combined seat control valve of this company with a gear electric actuator is a control element having β€œ1” and providing a balancing automatic function.

Why do I need a three-way valve with an electric actuator?

This is the most basic solution for creating a comfortable hot water supply. Such valves are best used in single pipe riser systems, as they provide installation of the closing section and convenient connection to the required device. Such a three-way valve with an electric actuator is simple to operate, and also indispensable for the safe use of warm water. It has a handle equipped with a locking system.

In application, the most interesting is the valve, in which the axes in thermostatic heads are perpendicular to the wall. It should be noted that for radiator assemblies with similar equipment, the hydraulic characteristics are determined by the pressure difference between the return and supply pipes in the closing section. They depend on the flow rate of the coolant located in the riser, the adjustment for leakage, in addition, on the hydraulic characteristics of the direct heating devices.

This valve is designed for underfloor heating and hot water. Moreover, it can also be used in heating.

Main function

The main task of a thermostatic valve is to dilute fluid flows of different temperatures to produce the required temperature at the outlet of the mixture.

Therefore, it can be a dilution of cold water with warm water in a hot water supply, so that a stable temperature of fifty degrees of water can be obtained from the tap at the outlet. But for a warm floor, the coolant is diluted from the return pipe with the coolant from the supply pipe (to obtain a temperature of thirty degrees).
