The Sun Hydraulics FPHKMEN512 (FPHKMEN512) is a pilot-operated, normally closed, electro-proportional throttle valve featuring a reverse free flow check. This advanced hydraulic component operates by energizing the coil, which generates an opening force on the pilot stage to vent the main stage poppet, allowing for proportional opening. The metered flow direction is from port 1 to port 2, with reverse free flow capability from port 2 to port 1. Designed for high-pressure environments, it can withstand pressures up to 5000 psi. The valve's coils are interchangeable with Sun's other solenoid-operated valves and can be mounted in either direction on the tube for flexible installation. The FPHKMEN512 incorporates Sun's floating style construction, minimizing internal parts binding due to excessive torque or machining variations. It offers several manual override options, including a momentary twist override that shifts the valve by twisting the manual override clockwise by 90 degrees. For optimal performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100 and 250 Hz. The valve has a capacity of up to 60 gpm (240 L/min) and features a low maximum leakage rate of just 10 drops/min at 5000 psi. This model fits into a T16A cavity and belongs to Series 3 of Sun Hydraulics' product line. It requires an installation torque between 150-160 lbf ft (203-217 Nm) and has a hex size of 1\u00bc inches (31.8 mm). With its robust design and versatile capabilities, the FPHKMEN512 is suitable for various hydraulic applications requiring precise control over fluid flow 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.
