The KFDG4V52C50NZMUH720 valve belongs to the Directional Control Valves series from Vickers and is installed in hydraulic automation systems to direct flow between actuator ports. It is solenoid-controlled, so spool movement is triggered electrically rather than mechanically. The coil is rated for 24 V DC, allowing direct operation from common machine control supplies, and it connects through an ISO 4400 (DIN 43650) plug that supports quick field replacement. When the valve is in the neutral position, all ports are blocked to hold load pressure. A single-stage layout keeps the response straightforward and limits pressure drop. The body bolts to an ISO 4401-05 (NG10) subplate, making it interchangeable with other NG10 components. Rated flow is 50 L/min through ports A and B, and maximum system pressure is 315 bar, enabling use on medium-to-high pressure circuits.
Meter-in/meter-out metering lets the circuit control extension and retraction speeds independently, while a 210 bar tank port rating tolerates elevated return pressures without leaking. The valve includes a feedback sensor that reports spool position for closed-loop applications, and it demands fluid cleanliness of ISO 4406 17/15/12 to prevent wear. Viton seals resist high temperature petroleum or synthetic fluids. Overall size is compact at 154.940 mm in length, 50.800 mm in width, and 65.532 mm in height, which eases manifold spacing and enclosure design.
