The Sun Hydraulics FPHKECN812 (FPHKECN812) is a pilot-operated, normally closed electroproportional throttle valve with a reverse free flow check. This valve is designed to provide efficient control of hydraulic flow, allowing metered flow from port 1 to port 2, and enabling reverse free flow from port 2 to port 1. It operates effectively under pressures up to 5000 psi, making it suitable for demanding hydraulic applications. The valve's coil is interchangeable with Sun's other full-flow solenoid-operated valves and can be mounted in either direction on the tube. For enhanced performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. This cartridge valve features several manual override options, including a momentary-twist override that allows the operator to shift the valve by twisting the manual override clockwise by 90 degrees. Depending on specific circuit requirements, a reverse free flow check bypassing the compensator may be necessary when using this valve with an external compensator. The FPHKECN812 incorporates Sun's floating style construction, which minimizes potential internal part binding due to excessive installation torque or cavity/cartridge machining variations. Key specifications include a T16A cavity size, Series 3 classification, and a capacity of up to 60 gpm (240 L/min). The maximum valve leakage at 110 SUS (24 cSt) is restricted to 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The manual override requires a force of approximately 5 lbs/1000 psi at Port 1 (33 N/100 bar). The solenoid tube diameter measures .75 inches (19 mm), while the valve hex size is set at 1\u00bc inches (31.8 mm). Installation torque ranges between 150-160 lbf ft (203-217 Nm), and the model weight is approximately 1.50 lb (0.70 kg), increasing to around 2.00 lb when equipped with a coil.

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.
