The Sun Hydraulics FPHKECN512 (FPHKECN512) is a pilot-operated, normally closed, electroproportional throttle valve with a reverse free flow check feature. This versatile cartridge valve is designed to manage fluid flow by generating an opening force on the pilot stage when the coil is energized, thereby 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. It operates efficiently under pressures up to 5000 psi and can handle a capacity of up to 60 gpm (240 L/min). The valve's coils are interchangeable with other full-flow solenoid-operated valves from the same manufacturer and can be mounted in either direction on the tube. The FPHKECN512 model offers several manual override options, including a momentary twist override that allows operators to shift the valve by twisting it clockwise by 90 degrees. For optimal performance, it is recommended that this valve be used in conjunction with an amplifier featuring current sensing and adjustable dither between 100-250 Hz. Additionally, depending on specific circuit requirements, a reverse free flow check bypassing the compensator might be necessary when using this model with an external compensator. This model incorporates floating style construction to minimize potential binding of internal parts due to excessive installation torque or variations in cavity/cartridge machining. It has a nominal deadband as a percentage of input at approximately 25% and features manual override stroke of .06 inches (1.50 mm). The seal kit for this cartridge uses Viton material and has specific part numbers for both cartridge and coil seal kits.

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.
