Products Detail

Advantage of this Handwheel Operated Center Line Flange Butterfly Valve:The center of rotation of the flange disc (ie, the center of the valve stem) is located on the centerline of the valve body and the sealing surface section of the disc. The seat is made of synthetic rubber. When closed, the outer sealing surface of the disc is pressed against the synthetic rubber seat, so that the valve seat is elastically deformed, thereby forming an elastic force as a sealing specific pressure to ensure the sealing of the butterfly valve. The sealing structure of the flange butterfly valve adopts PTFE and synthetic rubber to form a composite valve seat. The characteristic is that the elasticity of the valve is still provided by synthetic rubber and utilizes the low friction coefficient of polytetrafluoroethylene, which is not easy to wear and is not easy to aging. The life of the butterfly valve is improved.
