Cast Steel Piston Check Valves

Piston check valves are similar in configuration to globe valves, except that the disc or plug is automatically operated. The main advantage of the piston (lift) check valve lies in its simplicity, and as the cone is the only moving part, the valve is robust and requires little maintenance.
