KFDG4V333C13NZVMU1H720

The KFDG4V333C13NZVMU1H720 valve belongs to the Proportional Valves series produced by Vickers for accurate hydraulic automation. It is solenoid controlled, so spool movement follows electric current signals and allows proportional flow adjustment without pilot pressure changes. A coil rated at 24 V DC matches standard mobile and industrial power supplies, making electrical integration straightforward. The spring centered build returns the spool to its neutral position when power is removed, providing fail-safe blockage of actuator ports. Because no manual override is fitted, unintended hand actuation is prevented during maintenance. The model includes a feedback sensor that reports spool position to the external controller, enabling closed-loop flow regulation. On-board electronics are absent, which shifts signal processing to a remote drive card and reduces valve body temperature. Maximum operating pressure is 350 bar, permitting use in high-pressure circuits such as presses or injection machines. An interface pattern of ISO 4401-03 / NFPA D03 / CETOP 3 lets the valve mount on widely adopted subplates for quick replacement.

Nominal port flow is 13 L/min, supplying cylinders or motors that require moderate volume while maintaining proportional control. Meter-in and meter-out metering lets the designer tune both extension and retraction speeds for consistent motion. The valve accepts antiwear oils and non-alkyl phosphate esters, allowing operation in systems that avoid zinc or in fire-resistant environments. To maintain functional clearances, supplied fluid must meet an ISO 4406 cleanliness code of 17/15/12, so filtration should be sized accordingly. Electrical connection is provided through an ISO 4400 form plug, and the fitted connector seals contacts against moisture for reliable coil energization. External dimensions measure 270.002 mm in length, 48.006 mm in width, and 87.122 mm in height, facilitating installation in compact manifolds. These dimensions also guide clearance planning inside machine guards. Together, the flow rating, metering scheme, fluid demands, connection style, and size data outline how the KFDG4V333C13NZVMU1H720 integrates into a hydraulic circuit and what auxiliary components are required.
