Technical specifications

This valve assembly consists of a normally-open restrictive style compensator on the P port and a shuttle that senses pressure from the higher of the 2 work ports. Its purpose is to provide a relatively constant pressure drop across the directional valve thus isolating the directional valve spool from high flow forces. This is accomplished by throttling the supply into the P port. The constant drop creates a pressure compensated flow control out of the directional valve.

  • This assembly is normally used in a multi-station load-sense system or with a pressure compensated pump.
  • The pressure differential across the orifice (directional valve) varies with flow and system pressure. It is at its highest at zero flow and drops with increasing flow.
  • Another term for this assembly is a hydrostat.
  • Body Type

  • Why doesn't Sun anodize their aluminum bodies?
  • How big is a drop of hydraulic oil?  
  • Direct acting or pilot operated - what do I use?
  • Seal retainer plate is not required for this assembly.
  • For detailed information regarding the cartridges contained in this assembly, click on the models codes shown in the Included Components tab.
  • Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
