Control valve with electric actuator

Regulating valve with electric drive is pipeline equipment designed for automatic control of flow by changing the valve's passage area. In addition to electric drive, a regulating valve may be equipped with a thermal, thermoelectric, pneumatic, or hydraulic drive.

Application area

Regulating valves are used in automation systems as indirect regulators of temperature, pressure, or water flow.

In building engineering systems, regulating valves are used:

• In heating systems, a valve controlled by an electric drive by a signal from an electronic controller allows for weather-dependent regulation and programmable reduction of thermal power during non-working hours.
• In hot water supply systems, regulating valves with electric drive are used to maintain a constant water temperature at the outlet of the water heater as an indirect temperature regulator.
• In ventilation systems with heating or cooling of air, regulating valves are used to control the heat/cooling transfer of a water-air heat exchanger (calorifier).

Equivalent names

• Two-way valve
• Saddle valve
• Automatic regulator
• Thermal flow controller

Possible replacements

In systems where a constant water temperature is required according to the technological process, a regulating valve with electric drive can be replaced with a direct-acting temperature controller.

If a regulating valve is used to control the mixing of the heat carrier, it can be replaced with a three-way valve with electric drive.

If the regulator is expected to operate in a two-position mode (open/closed), it can be replaced with any shut-off valve with an electric drive.

In cases where automatic water flow change is not required and smooth manual control is allowed, a balancing valve can be used instead.
