API 602 Standard Reduced Port Socket Weled Forged Steel Piston Type Lift Check Valve

Lift Check vale is installed in pipeline systems, its main function is to prevent medium from flowing backwards. And it is a kind of automatic valve starting and closing relying on medium’s pressure.

Anciently, people mainly use model H44 flange connecting turning type check valve as well as model H41 flange connecting lifting type check valve, traditional check valves have big cubage, heavy liquid resistance, and their water hammer pressures are high when they are closed, hard to install or maintain, with short using life.
