Lift check valve

The seat design of a lift-Check valve is similar to a Globe valve. The disc is usually in the form of a piston or a ball.
Lift Check valves are particularly suitable for high-pressure service where velocity of flow is high. the disc is precisely guided and fits perfectly into the dashpot. Lift Check valves are suitable for installation in horizontal or vertical pipe-lines with upward flow.
