The rotary disc valves of type 12с are intended for the flow control of air and compatible stripped gases in the gas and air lines of the boiler unit.
The control is carried out through changing the area of passage section when turning the disc with the help of:
- an actuator of single-turn electric flanged actuator (МЭОФ) type
installed on the top trunnion; - an actuator of single-turn electric actuator (МЭО) type through the lever.
The full opening of the valve corresponds to the disc turning by an angle of 90 from the closed position.
