The KFDG4V333C20NZMU1H720 valve belongs to the Directional Control Valves series from Vickers and is intended to proportionally direct oil in automated hydraulic machinery. It fits the ISO 4401-03 (NFPA D03) subplate pattern, so it can be swapped with other valves that share the same manifold interface. The spool is arranged with P closed and A and B bleeding to T when centered, a feature that isolates pump pressure yet allows the work ports to depressurize during standby. Meter-in and meter-out metering let the user throttle flow in both directions for accurate actuator speed control. The unit passes a rated 20 L/min at a 5 bar differential, supporting medium-sized cylinders or motors. The P, A, and B passages tolerate continuous pressures up to 350 bar, whereas the T port is limited to 160 bar return pressure. Hysteresis stays below 1 percent of the maximum stroke, and a 0–100 percent step change is achieved in 18 ms, enabling tight position loops.
Electrical operating data are designed for continuous duty; the coil has a resistance of 1.87 Ω at 20 °C and may be supplied up to 2.7 A at 50 °C without exceeding its thermal limits, matching the 100 percent ED rating. Connection is made through an ISO 4400 (DIN 43650) plug, simplifying maintenance in common control cabinets. An IP65 enclosure protects the magnet housing against dust ingress and water jets, so the valve can be mounted in exposed machine areas where thorough wash-down is required. Reliable service is maintained at ambient temperatures as high as 60 °C. Electromagnetic emission meets EN 50081-2, and immunity meets EN 50082-2, allowing the valve to coexist with sensitive control electronics on modern production lines. These characteristics combine mechanical precision with robust electrical design to ensure consistent flow control in demanding hydraulic automation tasks.
