300LB Stainless Steel Wafer Lift Check Valve DN15-300 for Water, Oil, Gas, Air Applications

XIDELONG H71H lift check valve designed for high-pressure applications with superior flow control performance.

Dimensions in millimeters:

Lift check valves are engineered for high-pressure applications where flow velocity is significant. The precisely guided disc fits perfectly into the dashpot, making these valves suitable for installation in horizontal or vertical pipelines with upward flow.

Flow must always enter below the seat. The piston or ball is raised within guides from the seat by upward flow pressure. When flow stops or reverses, both backflow and gravity force the piston or ball back onto the valve seat.

• Significantly lighter weight compared to conventional flanged end swing check valves
• Short overall length enables easy installation in horizontal or vertical pipelines without special pipe support
• Seat is fitted in the body to prevent contact with flow, extending service life
• Large orifice size minimizes head loss, reducing pump energy consumption
• Compact face-to-face dimension facilitates installation between standard gasket and line flanges
