The Sun Hydraulics FPHKEEN212N (Material Number: FPHKEEN212N) is a pilot-operated, normally closed electroproportional throttle valve with reverse free flow check capabilities. Designed to handle pressures up to 5000 psi, this valve efficiently manages the flow of hydraulic fluid. When the coil is energized, it generates an opening force on the pilot stage, venting the main stage poppet to open proportionally for metered flow from port 1 to port 2 and allowing reverse free flow from port 2 to port 1. The FPHKEEN212N is compatible with interchangeable coils from Sun's solenoid-operated valve range and can be mounted in either direction on the tube. For enhanced performance, it is recommended to use an amplifier with current sensing and adjustable dither, adjustable between 100-250 Hz. The valve features several manual override options, including a momentary-twist override that allows manual operation by twisting clockwise 90 degrees. If circuit requirements dictate, a reverse free flow check bypassing the compensator may be necessary when using this valve with an external compensator. Constructed using Sun's floating style design minimizes internal part binding risks due to excessive installation torque or machining variations in the cavity/cartridge. Additional specifications include a capacity of 60 gpm (240 L/min), a recommended dither frequency of 100 Hz, and a maximum valve leakage at 110 SUS (24 cSt) of 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The valve requires an installation torque of 150-160 lbf ft (203-217 Nm) and weighs approximately 1.50 lb without coil and 2.00 lb with coil. Seal kits are available for both cartridge and coil assemblies using Viton material for durability under high-pressure conditions.

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.
