The Sun Hydraulics FPHKMCN724N (FPHKMCN724N) is a pilot-operated, normally closed electroproportional throttle valve featuring reverse free flow check functionality. When the coil is energized, it generates an opening force on the pilot stage, which in turn vents the main stage poppet to open proportionally. This allows metered flow from port 1 to port 2 while facilitating reverse free flow from port 2 to port 1. The valve is capable of operating under pressures up to 5000 psi and can accommodate a maximum capacity of 60 gpm (240 L/min). Coils are interchangeable with other full flow solenoid-operated valves from Sun Hydraulics and can be mounted in either direction on the tube. For optimal performance, it's recommended that an amplifier with current sensing and adjustable dither\u2014between 100 and 250 Hz\u2014be used. The valve incorporates Sun's floating style construction to minimize potential binding of internal parts due to excessive installation torque or machining variations. It also offers several manual override options, including a momentary twist override option for manual operation by twisting clockwise by 90 degrees. The cartridge fits within cavity T-16A and requires an installation torque between 150-160 lbf-ft (203-217 Nm). Additional specifications include a solenoid tube diameter of .75 inches (19 mm), a valve hex size of 1\u00bc inches (31.8 mm), and a nominal deadband as a percentage of input at approximately 25%. The product weighs approximately 1.50 lb without the coil and includes Viton seal kits for both cartridge and coil components.
