The Sun Hydraulics FPHKMCV212 (FPHKMCV212) is a pilot-operated, normally closed electroproportional throttle valve with a reverse free flow check feature. Designed to handle pressures up to 5000 psi, it provides metered flow from port 1 to port 2 while allowing reverse free flow from port 2 to port 1. This valve is versatile, with interchangeable coils compatible with Sun's other full-flow solenoid-operated valves, and can be mounted in either direction on the tube. For optimal performance, an amplifier with current sensing and adjustable dither between 100-250 Hz is recommended. The valve includes multiple manual override options, including a momentary twist option that allows shifting by twisting the manual override clockwise by 90 degrees. Depending on specific circuit requirements, a reverse free flow check bypassing the compensator may be necessary when using this valve with an external compensator. The FPHKMCV212 features Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity-cartridge machining variations. It fits into a T16A cavity and belongs to Series 3, offering a capacity of up to 60 gpm (240 L/min). The maximum valve leakage at 110 SUS (24 cSt) is limited to 10 drops/min (0.7 cc/min) at 5000 psi (350 bar). The manual override requires a force of approximately 5 lbs/1000 psi at Port 1 and has a stroke of .06 inches (1.50 mm). With a solenoid tube diameter of .75 inches (19 mm) and hex size of 1\u00bc inches (31.8 mm), the installation torque ranges between 150-160 lbf ft (203-217 Nm). The model weighs about 1.50 lb without coil and approximately 2.00 lb with coil included.
