The Sun Hydraulics FPHKXCN2F12V (Material Number: FPHKXCN2F12V) is a sophisticated pilot-operated, normally closed, electroproportional throttle valve with a reverse free flow check. This component is designed to handle pressures up to 5000 psi and is capable of metering flow from port 1 to port 2, while allowing reverse free flow from port 2 to port 1. It features interchangeable coils that can be mounted in either direction on the tube, providing flexibility in installation. The valve incorporates Sun's floating style construction, which reduces the risk of internal binding due to excessive torque or machining variations. For optimal performance, it is recommended to use an amplifier with current sensing and adjustable dither between 100-250 Hz. The valve offers several manual override options, including a momentary twist override that allows operation by twisting the override clockwise by 90 degrees. The FPHK model may require a reverse free flow check bypassing the compensator if used with an external compensator based on circuit requirements. The valve fits into a T16A cavity and belongs to Series 3 with a capacity of 60 gpm (240 L/min). It has a maximum leakage rate of 10 drops/min at 5000 psi and requires an override force of approximately 5 lbs/1000 psi at Port 1. The solenoid tube diameter measures .75 inches (19 mm), and the valve has a hex size of 1\u00bc 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 comes with Viton seal kits for both cartridge and coil applications for enhanced durability and sealing performance under various conditions.
