    This assembly consists of a bypass/restrictive, fixed-orifice, priority flow control which takes an input flow at port P and uses it to satisfy the priority flow at port CF. If the input flow exceeds the priority flow requirement, the excess is bypassed out port EF. The bypass flow may be used in a secondary circuit. The relief valve protects the controlled flow from over-pressurization, relieving excess flow out of port T.

    • Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
    • 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.
    • Pressure at the bypass port (port EF) may exceed pressure at the priority port (port CF).
    • Maximum pressure at the priority port should be limited to 3000 psi (210 bar).
    • Bypass flow is not available until priority flow requirements are satisfied.
    • Relief model RPEC is adjustable within 100 to 3000 psi (7 - 210 bar) with a factory setting of 1000 psi (70 bar).

    • 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.
