Hydraulic Barrier Check Valve

This back-to-back check valve assembly has been developed for use on hot stab applications to prevent leakage of low pressure compensated hydraulic fluid.

The valve is configured to provide a zero-leak barrier to fluids below the specified cracking pressure and permits equal flow in either direction with minimal restriction.

The compact design allows fitment of multiple valves in close proximity to each other as required for direct connection to either male or female multi-port hot stab assemblies.

Category:

– Zero leak design up to specified cracking pressure.

– Suitable for use with all mineral based and environmentally friendly ester based hydraulic oils, as well as all water glycol based control system fluids.
