The Sun Hydraulics FPHKXCN224N (FPHKXCN224N) is a pilot-operated, normally closed, electroproportional throttle valve designed for precise flow control in hydraulic systems. This versatile valve features a reverse free flow check, allowing metered flow from port 1 to port 2 and free flow in the opposite direction. It can operate under high pressures of up to 5000 psi, making it suitable for demanding applications. The valve's coil is interchangeable with other full-flow, solenoid-operated valves from Sun Hydraulics and can be mounted on the tube in either direction, providing flexibility in installation. For optimal performance, it is recommended to use an amplifier with current sensing and adjustable dither, which should be set between 100-250 Hz. The FPHKXCN224N also offers various 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. In scenarios where an external compensator is used, a reverse free flow check may be necessary depending on circuit requirements. The valve incorporates Sun's floating style construction to minimize internal binding due to excessive torque or machining variations. It fits into a T16A cavity and belongs to Series 3 with a capacity of 60 gpm (240 L/min). The valve has a maximum leakage rate of 10 drops/min at 5000 psi and requires a manual override force of 5 lbs/1000 psi at Port 1. Weighing approximately 1.50 lb without the coil and up to 2.00 lb with it, this valve offers robust performance while maintaining ease of installation and operation through its compact design.
