Three-way valve with electric drive: types and functions

Today, one can not imagine a heating system without balancing, shut-off and regulating valves. In this case, thermostatic valves are control valves that perform 2 functions: it provides a comfortable temperature in the room, and also monitors energy savings. It should be noted that the valve regulating three-way with the electric drive can be installed on a separate radiator, as well as on the whole branch, which supplies the coolant to various radiators. 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. If the temperature drops below a certain one, the coolant begins to circulate in the radiator, which leads to energy savings of thirty percent.

Groups of three-way valves

All valves intended for two-pipe systems are divided into 2 groups - without preliminary and with pre-setting. It is obvious that a three-way thermostatic valve without preliminary adjustment ensures that basically all the radiators on the riser will have an equal coolant flow rate. In this case, it must be installed in the first place, depending on the heat loss of the room, which must be compensated. Consequently, it is more economically advantageous to use a three-way valve with an electric drive with pre-setting.

It should be taken into account that the adjustment with their help is carried out very easily, since the values located on the valve head can easily be checked and set the required temperature.

There is also an alternative configuration option with a vent located at the outlet of the radiator, although this method is slightly more complicated. Since for the beginning it is required to completely close, and then open to the required number of revolutions, it is obvious that in this case it is quite problematic to make control. Consequently, many such valves are not tuned, which leads to an unnecessary expense of the coolant.

We select a three-way valve with an electric drive

Recently, the market provides a wide range of control valves, while it should not be forgotten that not all equipment is of excellent quality. Thus, the three-way valve with electric drive Danfoss is designed to provide a remote distribution of flows between all consumers with the highest degree of efficiency. The combined seat regulating valve of this company with geared motor drive is a control element having "1" and providing a balancing automatic function.

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

This is the most basic solution for creating comfortable hot water supply. Such valves are best used in stand-alone single-pipe systems, as they provide the installation of a closing section and convenient connection to the required device. Such a three-way valve with electric drive is easy 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, whose axes in thermostatic heads are perpendicular to the wall. It should be noted that in radiator units with similar equipment, the hydraulic characteristics are determined by the pressure difference between the return and supply nozzles in the closing section. They depend on the flow of the coolant located in the riser, the settings for flowing, in addition, from the hydraulic characteristics of the direct heating devices.

This valve is designed for warm floors and hot water supply. In this case, it can also be used in heating.

Main Function

The main task of the thermostatic valve is dilution of liquid flows of different temperatures for the emergence of the mixture at the desired temperature.

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