The Sun Hydraulics FPHKMEN2B12A (FPHKMEN2B12A) is a sophisticated pilot-operated, normally closed, electroproportional throttle valve featuring reverse free flow check capabilities. This valve is designed to handle pressures up to 5000 psi and provides metered flow from port 1 to port 2, with reverse free flow from port 2 to port 1. It incorporates Sun's floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or machining variations. The FPHKMEN2B12A is compatible with interchangeable coils from Sun's range of full-flow solenoid-operated valves, allowing for flexible installation options. 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 the operator to shift the valve by twisting the manual override clockwise by 90 degrees. This model fits into a T16A cavity and belongs to Series 3, with a capacity of up to 60 gpm (240 L/min). It has a maximum valve leakage rate of 10 drops/min at 5000 psi and requires a manual override force of approximately 5 lbs/1000 psi at Port 1. The FPHKMEN2B12A weighs approximately 1.50 lb without the coil and about 2.00 lb when equipped with it. It also includes Viton seal kits for both cartridge and coil components for enhanced durability under various operating 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.
