Parker Bestobell’s range of cryogenic lift check and swing check valves feature an innovative loose flange bolted bonnet design that allows for thermal expansion and contraction, therefore eliminating leakage.

Available in Stainless Steel and Bronze, Parker Bestobell’s check valves are fitted with a swing return, allowing for use in any position. The PTFE seal incorporated into the valve disc ensures a drop tight shut off at ambient temperatures. With the swing check valve, wide openings also allow high flow rates at low-pressure drops.  

Standardised parts are used in Parker Bestobell’s swing valves, globe, ball and gate valves. Parker Bestobell’s lift check valves are often specified in conjunction with globe valves and swing check valves would be used in conjunction with gate or ball valves.

The lift check valves feature a cone seat design for zero leak shut off, therefore maximising safety and performance.
