The Sun Hydraulics FPHKEEV512 (FPHKEEV512) is a pilot-operated, normally closed electroproportional throttle valve with reverse free flow check functionality. This valve is designed for applications requiring precise flow control and can handle pressures up to 5000 psi. It features metered flow from port 1 to port 2 and allows reverse free flow from port 2 to port 1. The valve's coil can be interchanged with other full-flow, solenoid-operated valves by Sun Hydraulics 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 FPHKEEV512 includes several manual override options, such as the momentary-twist override that allows the operator to shift the valve by turning the manual control clockwise by 90 degrees. Depending on circuit requirements, a reverse free flow check may be necessary when using this valve with an external compensator. Its floating style construction minimizes potential internal binding due to excessive installation torque or variations in cavity-cartridge machining. The cartridge fits into a T16A cavity and belongs to Series 3, offering a capacity of up to 60 gpm (240 L/min). With a maximum leakage rate of 10 drops/min at 5000 psi, it ensures efficient operation under high-pressure conditions. Additional specifications include a solenoid tube diameter of .75 inches (19 mm), a valve hex size of 1\u00bc inches (31.8 mm), and an installation torque range of 150-160 lbf ft (203-217 Nm). The model weighs approximately 1.50 lb without the coil and around 2.00 lb with the coil installed, utilizing Viton seal kits for both cartridge and coil components for enhanced durability and reliability in demanding environments.

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.
