What's Cast steel piston check valve ?

 Cast steel piston check valve is designed to prevent the reversal of flow in a piping system.it's commonly used in piping systems in which globe valves are being used as a flow control valve. They have similar seating arrangements as globe valves.Lift check valves are suitable for installation in horizontal or vertical lines with upward flow.

They are recommended for use with steam, air, gas, water, and on vapor lines with high flow velocities.the lift check valves are normally designed with spring,it's closed by default, requiring more pressure to open their door and allow fluid through.

A Cast steel piston check valve is a valve which prevents the suction line from running empty, e. g. after the pump has been stopped. Priming the pump prior to a re-start is therefore no longer necessary.Lift check valves
