The Sun Hydraulics FPHKEEN612 (Material Number: FPHKEEN612) is a sophisticated pilot-operated, normally closed electroproportional throttle valve with a reverse free flow check. This valve functions by energizing the coil, which generates an opening force on the pilot stage, venting 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. Designed for high-pressure applications, it operates efficiently at pressures up to 5000 psi and supports a flow capacity of up to 60 gpm (240 L/min). The FPHKEEN612 valve is compatible with interchangeable coils from Sun's range of full flow solenoid-operated valves, allowing flexibility in installation direction on the tube. For optimal performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The valve offers several manual override options, including a momentary-twist override that permits manual operation by twisting clockwise 90 degrees. Depending on specific circuit requirements, a reverse free flow check bypassing the compensator might be necessary when using this model with an external compensator. The FPHKEEN612 incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or cavity/cartridge machining variations. It fits into cavity T16A and belongs to Series 3. The valve features a nominal deadband percentage of input at approximately 25%, ensuring precise control in hydraulic systems. Installation requires a torque setting between 150-160 lbf ft (203-217 Nm), and its compact design weighs approximately 1.50 lbs without the coil and around 2.00 lbs with it attached.

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.
