Technical specifications

This assembly consists of a bypass/restrictive, fixed-orifice, priority flow control which takes an input flow at port A (in) and uses it to satisfy the priority flow at port A (out). If the input flow exceeds the priority flow requirement, the excess is bypassed out port T. The reverse flow check provides unrestricted flow out of port A.

  • The sharp-edged orifice design minimizes flow variations due to viscosity changes.
  • The tuneable control option provides +/- 25% variation from the nominal factory pre-set flow. Turn the adjustment clockwise to increase.
  • Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
  • Both priority and bypass flow are usable up to the system operating pressure.
  • Bypass flow is not available until priority flow requirements are satisfied.
  • Maximum pressure at the priority port should be limited to 3000 psi (210 bar).

  • Stack height value in technical data table includes seal retainer plate.
  • This installation requires a seal retainer plate and seal kit which are purchased separately. See "Related Accessories" section.
  • 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.
