Lift Check Valve
Parri lift check valve only allows medium to flow in one direction. when medium flows into the body as indicated by the arrow on the body, pressure of the medium acts on the disc to generate an upward thrust. When medium thrust is greater than the gravity of the disc, the valve opens；When pressure of the medium after the valve acts on disc and the gravity of the valve itself is greater than pressure before the valve, the valve is closed to prevent the medium from flowing backward. The flow passage of lift check valve is relatively narrow, and pressure loss of the medium after passing through disc is large. Disc can be metal sealed structure, or a soft sealed structure such as a rubber pad or a rubber ring on the disc.
