The control valves with butterfly dampers of type 12с are intended for the flow control of water steam, gas and air.

The control is carried out by means of changing the area of passage section between the body and the butterfly damper when turning it.
The full opening of the valve corresponds to the lever turning by an angle of 75 from the closed position.
