Lift Check Valves—50 Series
Swagelok® lift check valves limit reverse flow under pressures up to 6000 psig (413 bar) and temperatures up to 900°F (482°C). Forward flow lifts the poppet, opening the valve. Reverse flow seats the poppet against the orifice, closing the valve. The Swagelok lift check valve is gravity assisted and must be mounted horizontally, with bonnet nut on top.
