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.

Standard crack pressure: 5 bar (72.5psi) – in both directions (other or asymmetric crack pressures available upon request).

Max Working Pressure: 690 bar (10,000 psi).

Max Flow Rate: 25 LPM (6.57 USGM).

Supplied c/w 1/8” NPT male and 1/4” OD Twin Ferrule end connectors. Valve body features ¼” BSPP female ports allowing easy replacement of end fittings to suit your specific applications, if required.

Operational Temperature rating: -20 – 70 Deg C.

Max depth rating – Unlimited – not affected by depth.

Weight (in air): 204 grams

– Dimensions: 65mm Long x 21mm Outside Diameter (excluding fittings).
