The Sun Hydraulics FPHKXEN812N (FPHKXEN812N) is a pilot-operated, normally closed, electroproportional throttle valve with a reverse free flow check feature. This valve is designed to control fluid flow in hydraulic systems by energizing the coil, which generates an opening force on the pilot stage, allowing the main stage poppet to open proportionally. It facilitates metered flow from port 1 to port 2 and allows reverse free flow from port 2 to port 1. The valve can operate under pressures up to 5000 psi and boasts interchangeable coils compatible with Sun's other solenoid-operated valves. For optimal performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The valve includes several manual override options, such as the momentary twist override option E, which enables manual shifting by twisting clockwise 90 degrees. The FPHKXEN812N features a T16A cavity and belongs to Series 3 with a capacity of up to 60 gpm (240 L/min). It has a maximum valve leakage of 10 drops/min at 5000 psi (0.7 cc/min at 350 bar) and requires a manual override force of approximately 5 lbs/1000 psi at Port 1. The solenoid tube diameter measures .75 inches (19 mm), while the hex size is 1\u00bc inches (31.8 mm). Installation torque ranges from 150-160 lbf ft (203-217 Nm). The model weighs around 1.50 lb without coil and increases to approximately 2.00 lb with coil included. This valve incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations in cavity or cartridge dimensions. Seal kits are available in Viton material for both cartridge and coil components under part numbers: Viton: 990016006 and Viton: 990770006 respectively.

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.
