Lift check valves are available for sour gas service. Materials are selected in accordance with NACE MR0175/ISO 15156.

Lift check valves limit reverse flow - forward flow lifts the poppet, opening the valve. Reverse flow seats the poppet against the orifice, closing the valve. The lift check valve is gravity assisted and must be mounted horizontally, with bonnet nut on top.

Lift check valves depend on gravity. In a lift check valve, the poppet is positioned so that forward flow through the valve lifts the poppet off of the valve seat. When higher pressure is felt on the outlet of the check valve, gravity pulls the poppet shut with the assistance of the fluid.
