The KFDG4V52C50NZMU1H720 valve belongs to the Directional Control Valves series and is produced by Vickers for use in hydraulic automation circuits that require directional change and accurate spool positioning. It is solenoid controlled, allowing electrical signals to shift the spool, while a spring centered build returns the element to its neutral position when power is lost. A 24 V DC coil integrates with standard machine power supplies, and ISO 4400 plugs provide a quick electrical connection without special tools. The mounting interface follows ISO 4401-05 (NFPA D05, CETOP 5), and the NG10 size fixes port dimensions for compatibility with common manifolds. Operation is permitted up to 315 bar, so the valve can be installed in high-pressure lines, and the absence of a manual override prevents unplanned mechanical actuation. An internal feedback sensor supplies spool position data to external control hardware.
The unit supports a rated flow of 50 L/min, giving stable performance for medium-capacity cylinders or motors, and its meter-in/meter-out metering lets designers tailor acceleration and deceleration independently. Compatibility with antiwear oils and non-alkyl phosphate esters broadens fluid choice, but cleanliness must be maintained at class 17/15/12 to protect precision lands. No on-board electronics are fitted, so an external amplifier must generate the drive current and process feedback signals. Physical dimensions of 335.026 mm in length and 106.172 mm in height help planners allocate space in compact power units or subplates. Together, these specifications establish the valve’s hydraulic capacity, installation envelope, and control requirements without adding unnecessary features.
