There Are Two Types Of Lift Check Valves:

Flow to lift check valves must always enter below the seat. The lift check valves (also known as piston check valves) have a guided plug which is lifted by the higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. Gate, globe, and check valves.

Discs Are Guided Along A Vertical Line So They Can Later Be Appropriately Reseated.

When the inlet pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow. It requires a cracking pressure to overcome gravity and/or a spring and the guide keeps the disc in a vertical line, so that the disc can be re. When the flow weakens, slows, reverses, or stops, gravity forces the disk or ball downward onto the seat.
