Lift Type Check Valve

Categories:High Pressure Seal Check Valve

Brief Introduction


Lift check valves are also called piston check valves. They are essentially globe valves without the stem and top works, allowing the disc to respond to flow rates and direction. The disc has linear movement and is typically body-guided with conical seating surfaces. Springs can be added above the disc to provide more closure force when the disc returns to its closed position.
