The Sun Hydraulics FPHKEEN912 (FPHKEEN912) is a versatile pilot-operated, normally closed, electroproportional throttle valve featuring a reverse free flow check. This valve is engineered to handle pressures up to 5000 psi and is designed for precise flow control applications. It operates by energizing the coil, which generates an opening force on the pilot stage, venting the main stage poppet for proportional opening. The metered flow occurs from port 1 to port 2, while reverse free flow is facilitated from port 2 to port 1. The FPHKEEN912 incorporates Sun's floating style construction, reducing the risk of internal component binding due to excessive installation torque or cavity-cartridge machining variations. The valve's design includes interchangeable coils compatible with Sun's other full-flow solenoid-operated valves, allowing flexibility in mounting direction. It also offers several manual override options, including a momentary-twist override that permits manual operation by twisting the override clockwise by 90 degrees. For optimal performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. This cartridge fits into a T16A cavity and belongs to Series 3 with a capacity of up to 60 gpm (240 L/min). Its maximum valve leakage at 110 SUS (24 cSt) is limited to 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The FPHKEEN912 requires a manual override force of approximately 5 lbs/1000 psi at Port 1 (33 N/100 bar), with a nominal deadband as a percentage of input set at around 25%. The solenoid tube diameter measures .75 inches (19 mm), with a valve hex size of 1-1/4 inches (31.8 mm). Installation torque ranges between 150-160 lbf ft (203-217 Nm), and it weighs approximately 1.50 lbs without coil and up to 2.00 lbs with coil included.

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.
