The hydraulically pilot operated check valves series RH for in-line mounting are proven components of Parker’s check valve product range which ensure a leak-free blocking of the flow and thus a reliable operation. They allow free flow in one direction (B to A), the counter flow is blocked (A to B). By applying pilot pressure the ball can be lifted from its seat and allows flow from A to B.

Most common use:
• Keeping cylinders leak-free in position, when spool type directional control valves are used
• Return line discharge, when return flow exceeds functional limits of directional control valve at differential cylinders
• As hydraulically activated drain or circulation valve

Markets:

• Industrial

Benefits:

• Spring-loaded balI seated valve – enables zero leakage
• Proven, robust design – ensures reliable operation
• Flexible, versatile mounting in any orientation – makes integration easy
• Short delivery time for most variations – no warehousing necessary
• Maximum operating pressure up to 700 bar

Applications:

• Suitable for general hydraulic applications
