Product Description

Original SUN FPFK-XDN Cartridge Valve Hydraulic Solenoid Valve
 

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.

• 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.
• 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.
