Butterfly Valves

Butterfly valves are used for regulating steam flow in case of pressure drop of more than 0.25 MPa. Flow of working medium is regulated by changing flow area between the body and swing gate during its rotation. Butterfly valves are not used as stop valves. Connection to pipeline – by welding. Operation – automatic control by means of remote or built-in electric drive.
