The Sun Hydraulics FPHKMEN712N (FPHKMEN712N) is a pilot-operated, normally closed electroproportional throttle valve designed to offer precise flow control with reverse free flow check capabilities. This valve is engineered to operate efficiently under pressures up to 5000 psi, making it suitable for demanding hydraulic applications. It features a unique design where energizing the coil creates an opening force on the pilot stage, venting the main stage poppet to open proportionally. The metered flow direction is from port 1 to port 2, while reverse free flow occurs from port 2 to port 1. The valve's cartridge incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. This model is compatible with interchangeable coils used in other full-flow solenoid-operated valves by Sun Hydraulics and can be mounted in either direction on the tube. It offers several manual override options, including a momentary twist override that allows manual shifting by twisting clockwise 90 degrees. For optimal performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The FPHKMEN712N fits into a T16A cavity and belongs to series 3 with a capacity of up to 60 gpm (240 L/min). Its maximum valve leakage at 110 SUS (24 cSt) is rated at 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The manual override force requirement stands at 5 lbs/1000 psi (33 N/100 bar) at Port 1. With a nominal deadband as a percentage of input set at 25%, this model weighs approximately 1.50 lb (0.70 kg), increasing slightly when equipped with a coil.
