The KFDG4V32C07NZVMU1H720 proportional valve is part of the Proportional Valves series produced by Vickers. It modulates hydraulic flow and pressure in automated circuits where precise actuation is required. The spool is spring centered so it returns to its neutral position when power is removed. The assembly follows a Sol A-Port A / Sol B-Port B orientation, which defines directional flow paths during operation. A 24 V DC coil energizes each solenoid to shift the spool. Mounting uses the ISO 4401-03 (CETOP 3, NFPA D03) pattern for interchangeability with common subplates. The design omits a manual override, so all shifts are electrically commanded. There are no onboard electronics, allowing remote control from external drivers. Under rated conditions the valve passes 7 L/min, equivalent to 1.80 US gpm, through the A and B ports.
The valve withstands working pressures up to 350 bar, supporting high-force actuators in industrial machines. It meters flow on both the inlet and outlet sides, a Meter In/Meter Out arrangement that improves stability during directional changes. Electrical connection is made through an ISO 4400 plug, simplifying coil replacement and maintenance. A built-in feedback sensor reports spool position to the external controller for closed-loop accuracy. The unit is intended for antiwear hydraulic oils and should be supplied with fluid cleanliness no worse than 17/15/12 to preserve spool and sleeve clearances. Overall height is 87.122 mm, while the body length measures 270.002 mm, allowing installation in compact manifolds without sacrificing flow capability.
