The Sun Hydraulics FPHKMCN (FPHKMCN) is a pilot-operated, normally closed, electroproportional throttle valve with a reverse free flow check feature. This advanced hydraulic component is designed to manage metered flow from port 1 to port 2 while allowing reverse free flow from port 2 to port 1. It operates efficiently under pressures up to 5000 psi, making it suitable for high-pressure applications. The valve's coils are interchangeable with other full-flow, solenoid-operated valves from Sun Hydraulics and can be mounted in either direction on the tube, offering flexibility in installation. For optimal performance, an amplifier with current sensing and adjustable dither between 100 and 250 Hz is recommended. The momentary-twist override option (option E) allows manual operation by twisting the override clockwise by 90 degrees. The FPHKMCN incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. It fits into a T16A cavity and belongs to Series 3, offering a flow capacity of up to 60 gpm (240 L/min). The valve features several manual override options including configurations without manual overrides for added versatility in various applications. With a nominal deadband as a percentage of input at around 25%, this valve ensures precise control in hydraulic systems. Additionally, the valve has low leakage rates at maximum pressure conditions and requires specific force for manual override operation depending on the pressure at Port 1. This model weighs approximately 1.50 lb without the coil and about 2 lb with it installed, making it lightweight yet robust for demanding environments.
