Technical specifications

This valve is a pilot-operated, normally closed, electro-proportional throttle with reverse free-flow check. Energizing the coil generates an opening force on the pilot stage which vents the main stage poppet to open proportionally. Metered flow is from port 1 to port 2 with reverse free flow from port 2 to port 1.

  • Capable of operating with pressures up to 5000 psi (350 bar).
  • Coils are interchangeable with Sun's other full flow, solenoid-operated valves and can be mounted on the tube in either direction.
  • For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.
  • Capacities rated at 200 psi (14 bar) differential and maximum rated coil current.
  • Depending on circuit requirements, a reverse free flow check bypassing the compensator may be needed when using the FPHK with an external compensator.
  • 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.
  • Coils are interchangeable with Sun's other full flow, solenoid-operated valves.
  • Depending on circuit requirements, a reverse free flow check bypassing the compensator may be needed when using the FPJP with an external compensator.
