The Sun Hydraulics FPHKXEN812 (FPHKXEN812) is a pilot-operated, normally closed, electroproportional throttle valve with a reverse free flow check. Designed to handle pressures up to 5000 psi, this valve is engineered for precise control in hydraulic systems. It operates by energizing the coil, which generates an opening force on the pilot stage, venting the main stage poppet to open proportionally. The metered flow is directed from port 1 to port 2, while reverse free flow occurs from port 2 to port 1. This versatile valve features interchangeable coils with other Sun 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. The FPHKXEN812 offers several manual override options, including a momentary twist override that allows manual shifting by twisting clockwise 90 degrees. It incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. With a cavity size of T16A and series 3 classification, it boasts a capacity of up to 60 gpm (240 L/min). The valve's maximum leakage at 110 SUS (24 cSt) is minimal at just 10 drops/min under full pressure conditions (5000 psi). Its installation requires a torque of 150-160 lbf ft (203-217 Nm), and it has a compact design with a model weight of approximately 1.50 lb (0.70 kg), increasing slightly when equipped with a coil. This product also includes Viton seal kits for both cartridge and coil configurations for enhanced durability and compatibility in various applications.

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.
