The Sun Hydraulics FPHKECV812N (FPHKECV812N) is a pilot-operated, normally closed, electroproportional throttle valve featuring a reverse free flow check. When the coil is energized, it creates an opening force on the pilot stage, venting the main stage poppet to open proportionally. This design allows for metered flow from port 1 to port 2 and reverse free flow from port 2 to port 1. The valve operates efficiently under pressures up to 5000 psi and supports a flow capacity of up to 60 gallons per minute (240 L/min). It incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations. The FPHKECV812N is compatible with interchangeable coils from Sun's solenoid-operated valves and can be mounted in either 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 allows manual shifting by rotating clockwise by 90 degrees. A reverse free flow check may be necessary when using this valve with an external compensator depending on circuit requirements. With a nominal deadband as a percentage of input at 25%, this valve features minimal leakage at maximum valve leakage rates of up to 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). It requires a manual override force of approximately 5 lbs/1000 psi at Port 1 (33 N/100 bar), and its solenoid tube diameter measures .75 inches (19 mm). The installation torque range for this model is between 150-160 lbf ft (203-217 Nm), ensuring secure mounting within its designated cavity T16A in Series 3 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.
