Motorized control valve

Motorized control valve is a pipeline fitting designed to control the flow of water by changing the area of the passage section. Regulating valves are used as an executive element in automation schemes for heating systems, hot water supply, and other technological processes.

The valve is controlled by an electric actuator and an electronic controller, based on the signal from a temperature, pressure, or flow sensor, depending on the function of the automation node. In addition to electric actuators, pneumatic, hydraulic, thermo-electric, or thermal drives can be used to control the regulating valve.

Application area

Regulating valves have become widespread with the increasing requirements for energy efficiency of building engineering systems, and now it is difficult to imagine a modern heat exchange station or boiler room without automatic control devices.

In building engineering systems, regulating valves are used for software control of heating systems, hot water supply, or convectors of air handling units.

Together with pressure sensors, regulating valves can be used as pressure regulators or constant flow regulators.

What can it be replaced with

If it is necessary to maintain a constant temperature, for example, in heating water for a hot water supply system, the regulating valve can be replaced with a direct acting temperature regulator.

In some cases, a two-way regulating valve can be replaced with a three-way valve with an electric actuator for separating or mixing the flow.

If the valve is not intended to operate with an intermediate position of the shutter (two-position regulation open/closed), the regulating valve can be replaced with any shut-off fitting with an electric actuator.

If there is no need for programmatic automatic control, a manual balancing valve can be used.

Regulating valves performing the function of indirect pressure or flow regulators can be replaced with a direct acting regulator with similar functions.
