The KFTG4V32B20NZMU1H720 valve belongs to the Proportional Valves series and is manufactured by Vickers for closed-loop hydraulic automation. Actuation is provided by a solenoid so the spool position responds to electrical current rather than manual levers, and the coil is designed for 24 VDC, allowing direct connection to common machine control power supplies. The valve mounts on an ISO 4401-03 (NFPA D03/CETOP 3/NG06) subplate, making it interchangeable with other NG06 devices in modular manifolds. It supports meter-in and meter-out control, enabling balanced acceleration and deceleration of actuators. A rated flow of 20 L/min defines the maximum volume it can regulate without exceeding accuracy limits, while a system pressure limit of 315 bar suits medium-pressure circuits in presses and tooling. Antiwear oils and non-alkyl phosphate esters are approved media, and operation requires oil cleanliness no worse than 17/15/12 to maintain spool accuracy.
The valve connects electrically through an ISO 4400 plug, simplifying removal for service without disturbing conduit. A built-in feedback sensor monitors spool position to maintain proportional response, while the design omits on-board electronics so the drive amplifier must reside in the cabinet. Because the plug and sensor are concentrated on the end cap, field replacement time is reduced. There is no manual override, which prevents accidental displacement during maintenance. Reverse flow check capability is not included, therefore external check elements are needed when back-flow blocking is required. Overall dimensions are controlled for compact installation: length is 225.044 mm, width is 48.006 mm, and height is 87.122 mm, allowing stacking in tight manifold spaces. These fixed limits aid engineers in planning clearances and mounting bolts when integrating the unit into hydraulic automation systems.
