Rotating Disc Valve Series 12s DN 200 - 1400 for Steam Flow Regulation

Steam butterfly valves are designed for steam flow regulation at pressure drop not more than 0,25 MPa. The gate is regulated by changing the area of the passage section between the body and the butterfly valve when it is rotated. Full opening of the gate corresponds to turning the lever by an angle of 75? from the closed position. Operating characteristics, material of construction, type of connection, control body depend on the technical requirements.
