The Sun Hydraulics FPHKECN4A12V (Material Number: FPHKECN4A12V) is a pilot-operated, normally closed, electroproportional throttle valve featuring a reverse free flow check. This advanced valve is designed to control hydraulic flow with precision, making it suitable for applications requiring metered flow from port 1 to port 2 and reverse free flow from port 2 to port 1. Capable of handling pressures up to 5000 psi, the valve operates optimally with an amplifier that includes current sensing and adjustable dither, recommended between 100-250 Hz. The valve's construction incorporates Sun's floating style design, which minimizes internal binding due to excessive installation torque or machining variations. It features a cavity T16A and has a series rating of 3 with a capacity of up to 60 gpm (240 L/min). The solenoid-operated coils are interchangeable with other Sun valves and can be mounted in either direction on the tube. For manual operation, various override options are available, including the momentary twist override option E, which allows the operator to shift the valve by twisting clockwise by 90 degrees. Depending on circuit requirements, a reverse free flow check bypassing the compensator may be necessary when used with an external compensator. The valve's hex size is 1-1/4 inches (31.8 mm), and it requires an installation torque of 150-160 lbf-ft (203-217 Nm). With a maximum leakage rate at specified conditions of about ten drops per minute at 5000 psi (0.7 cc/min at 350 bar), this model weighs approximately 1.50 lb without coil and around 2.00 lb with coil installed. A Viton seal kit is available under part number 990016006 for cartridge maintenance needs.

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.
