The Sun Hydraulics FPHKMEV2D12A (Material Number: FPHKMEV2D12A) is a pilot-operated, normally closed, electroproportional throttle valve with a reverse free flow check. This advanced hydraulic component is designed to manage fluid flow efficiently by energizing the coil, which creates an opening force in the pilot stage to vent the main stage poppet and allow proportional flow from port 1 to port 2. It also provides reverse free flow from port 2 to port 1. The valve can handle pressures up to 5000 psi and has a capacity of 60 gpm (240 L/min). Its interchangeable coils are compatible with other solenoid-operated valves from Sun Hydraulics and can be mounted in either direction on the tube. For optimal performance, it is recommended to use an amplifier featuring current sensing and adjustable dither, ideally between 100 Hz and 250 Hz. The FPHKMEV2D12A incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or cavity/cartridge machining variations. The valve comes with various manual override options, including a momentary twist override that allows operators to shift the valve by twisting the manual override clockwise by 90 degrees. It requires a manual override force of approximately 5 lbs/1000 psi at Port 1 and offers a nominal deadband as a percentage of input at around 25%. The cartridge fits into cavity T16A from Series 3 and has a maximum leakage rate of approximately ten drops per minute at full pressure (5000 psi). The valve's hex size measures at 1-1/4 inches (31.8 mm), with an installation torque ranging between 150-160 lbf ft (203-217 Nm).
