The Sun Hydraulics FPHKXEN71299 (FPHKXEN71299) is a pilot-operated, normally closed, electroproportional throttle valve featuring a reverse free flow check. This advanced hydraulic component is designed to handle pressures up to 5000 psi, making it suitable for demanding applications requiring precise flow control. The valve operates by energizing the coil, which generates an opening force on the pilot stage, venting the main stage poppet to open proportionally. Fluid flows metered from port 1 to port 2 with reverse free flow available from port 2 to port 1. The FPHKXEN71299 boasts several features that enhance its versatility and performance. It supports interchangeable coils with other Sun solenoid-operated valves and can be mounted in either direction on the tube. The valve also offers multiple manual override options, including a momentary-twist override that allows manual operation by twisting the 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. This cartridge incorporates Sun's floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or cavity machining variations. The valve fits into a T16A cavity and belongs to Series 3 with a capacity of up to 60 gpm (240 L/min). It has a nominal deadband of approximately 25% as a percentage of input and requires a manual override force of approximately 5 lbs/1000 psi at Port 1. With its robust design and versatile features, the Sun Hydraulics FPHKXEN71299 is well-suited for applications demanding high precision and reliability in hydraulic systems.
