FRDAXAV - Fixed orifice, bypass/restrictive, priority, flow control valve

Part Number: FRDAXAV

Manufacturer: Sun Hydraulics

DESCRIPTION:

Bypass/restrictive, fixed-orifice, priority flow controls take an input flow at port 1 and use it to satisfy the priority flow at port 3. If the input flow exceeds the priority flow requirement, the excess is bypassed out port 2. The bypass flow may be used in a secondary circuit.

  • Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
  • Maximum pressure at port 3 should be limited to 3000 psi (210 bar).
  • Both priority and bypass flow are usable up to the system operating pressure.
  • Priority remains relatively constant regardless of variation in input flow.
  • Bypass flow is not available until priority flow requirements are satisfied.
  • Pressure at the bypass port (port 2) may exceed pressure at the priority port (port 3).
  • The sharp-edged orifice design minimizes flow variations due to viscosity changes.
  • A tuneable adjustment control option provides up to +/- 25% variation from the nominal factory pre-set flow. Adjustment is done with +/- 3 turns of the adjust screw. Screw in (CW) to increase flow.
  • Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
