The valve control is carried out with the help of the following actuators:
- a single-turn electric actuator (МЭО) through the lever;
- multi-turn built-in electric actuators with a current position sensor
of single-turn electric flanged actuator (ПЭМ) type (ABS ZEIM
Automation), SAR (AUMA); - actuators of other manufacturers with standard connection units.

The special control valves of type 18с are used as controlled throttle units of FRPRDS and PRDS, as well as for the control
of the working medium pressure in steam and water pipelines.
Structural designs:
- globe control valves;
- control valves.
The valves are designed and manufactured considering
specific requirements of the customer to order.
