The swing type pressure seal check valves allow flow in one direction and prevent flow in the reverse direction. Swing check valves can fit on both horizontal and vertical (up flow) piping. The valves are designed for high temperature, high pressure service.
The pressure seal joint eliminates heavy flanges reducing weight. The seals are pressure assisted. The Higher the internal pressure the tighter the seal, Reliable body bonnet tightness obtained due to the technologically advanced pressure seal design.
