Casting Steel Butt Welded P.S.B Gate Valve

Casting steel butt welded P.S.B gate valve uses a pressure self-tightening seal in the middle cavity. The higher the internal cavity pressure, the better the sealing performance. Both ends of the branch pipe are welded to meet different connection requirements. The sealing surface of the gate and the valve seat is made of Stellite cobalt-based hard alloy, which is wear-resistant, high temperature resistant, corrosion resistant and scratch resistant.
