SUMMARY:  Cartridge

Add to Cart

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.
  • Coils are interchangeable with Sun's other full flow, solenoid-operated valves and can be mounted on the tube in either direction.
  • This cartridge has several manual override choices, including no manual override. See Option Configuration.
  • For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.
  • The momentary/twist override option "E" allows the operator to shift the valve by twisting the manual override clockwise 90 degrees.
  • 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.
