The Sun Hydraulics FPHKXCN4A12A (FPHKXCN4A12A) is a sophisticated pilot-operated, normally closed, electroproportional throttle valve with a reverse free flow check. This valve is designed to manage fluid flow efficiently by energizing the coil to open the pilot stage and vent the main stage poppet proportionally. It allows metered flow from port 1 to port 2 while providing reverse free flow from port 2 to port 1, making it versatile for various hydraulic applications. The valve can handle pressures up to 5000 psi and features interchangeable coils that can be mounted in either direction on the tube. For enhanced performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The valve also offers several manual override options, including a momentary twist override which allows manual shifting by twisting clockwise by 90 degrees. It incorporates Sun's floating style construction, minimizing internal parts binding due to installation torque or machining variations. The cartridge fits into a T16A cavity and has a capacity of up to 60 gpm (240 L/min). Its design ensures minimal leakage at maximum pressure and requires a manual override force of approximately 5 lbs/1000 psi at Port 1. The valve's hex size is 1-1/4 inches with an installation torque requirement of 150-160 lbf ft (203-217 Nm). Weighing approximately 1.50 lb without the coil and up to 2.00 lb with it, this model uses Viton seal kits for both cartridge and coil components, ensuring durability and reliability in demanding environments.
