The Sun Hydraulics FPHKECN71299 (FPHKECN71299) is a pilot-operated, normally closed, electroproportional throttle valve with a reverse free-flow check. When the coil is energized, it generates an opening force on the pilot stage, allowing the main stage poppet to open proportionally for metered flow from port 1 to port 2, while permitting reverse free flow from port 2 to port 1. This versatile valve can handle pressures up to 5000 psi and features interchangeable coils compatible with Sun's other full-flow solenoid-operated valves. The cartridge design includes various manual override options, such as a momentary-twist override that allows the operator to shift the valve by twisting the manual override clockwise by 90 degrees. For optimal performance, using an amplifier with current sensing and adjustable dither\u2014ranging between 100 and 250 Hz\u2014is recommended. The FPHKECN71299 incorporates Sun's floating-style construction to minimize potential binding of internal parts due to excessive installation torque or variations in cavity/cartridge machining. With a capacity of 60 gpm (240 L/min) and minimal maximum valve leakage at high pressure, this model is designed for efficient hydraulic system integration. The valve fits into a T16A cavity and belongs to Series 3. It requires a manual override force of approximately 5 lbs/1000 psi at Port 1 and has a deadband nominally set at 25% of input. Installation calls for torque between 150-160 lbf ft (203-217 Nm), ensuring secure placement without damage. The model weighs approximately 1.50 lb (0.70 kg), increasing slightly with coil attachment. For maintenance or replacement needs, Viton seal kits are available under part numbers provided for both cartridge and coil components.

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.
