The Sun Hydraulics FPHKECN724N (FPHKECN724N) is a pilot-operated, normally closed electroproportional throttle valve with a reverse free flow check feature. This valve is designed to operate with pressures up to 5000 psi and supports metered flow from port 1 to port 2, while allowing reverse free flow from port 2 to port 1. It incorporates Sun's floating style construction to minimize internal binding due to installation torque or machining variations. The valve is compatible with interchangeable coils from Sun's solenoid-operated valves, which can be mounted in either direction on the tube. It offers several manual override options, including a momentary twist override that allows the operator to shift 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 100-250 Hz. The valve fits into a T16A cavity and has a series capacity of 60 gpm (240 L/min). The maximum leakage at 110 SUS (24 cSt) is limited to 10 drops/min at 5000 psi (0.7 cc/min at 350 bar). The required manual override force is approximately 5 lbs/1000 psi (33 N/100 bar) for Port 1, with a nominal deadband of about 25% of input. The solenoid tube diameter measures .75 inches (19 mm), and the valve hex size is 1-1/4 inches (31.8 mm). Installation torque should be between 150-160 lbf ft (203-217 Nm). The model weighs approximately 1.50 lbs without the coil and increases to about 2.00 lbs when equipped with one. Seal kits are available in Viton material for both cartridge and coil components, ensuring reliable sealing performance under demanding conditions.
