This valve is a pilot-operated, normally closed, electro-proportional throttle with reverse free-flow check. Energizing
the coil generates an opening force on the pilot stage which vents the main stage poppet to open proportionally.
Metered flow is from port 1 to port 2 with reverse free flow from port 2 to port 1.

TECHNICAL FEATURES
Capable of operating with pressures up to 5000 psi (350 bar).
Coils are interchangeable with Sun's other full flow, solenoid-operated valves and can be mounted on the tube in either direction.
This cartridge has several manual override choices, including no manual override. See Option Configuration.

For optimum performance, an amplifier with current sensing and adjustable dither should be used. Dither should be adjustable between 100 - 250 Hz.
The momentary/twist override option "E" allows the operator to shift the valve by twisting the manual override clockwise 90 degrees.
Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage
the seals.
Spool capacities rated at 200 psi (14 bar) differential and maximum rated coil current.
Maximum Deadband (as a percentage of command) B Flow Rate = 28% D Flow Rate = 32%
Maximum Hysteresis at 200 psid (14 bar) B Flow Rate = 2.2 gpm (9 L/min.) D Flow Rate = 5.2 gpm (20 L/min.)
Minimum Capacity at 1000 psid (70 bar) B Flow Rate = 25 gpm (94 L/min.) D Flow Rate = 49 gpm (185 L/min.)
Depending on circuit requirements, a reverse free flow check bypassing the compensator may be needed when using the FPFK with an external compensator.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
