DG4V30BLMUB660EN21P10

The DG4V30BLMUB660EN21P10 valve belongs to the DG4 Directional Valves series and is produced by Vickers for hydraulic automation circuits. It shifts flow paths to start, stop, or change the direction of oil within a manifold. A wet armature solenoid drives the spool so the hydraulic fluid cools and lubricates the magnetic core during repeated shifts. The coil is terminated through an ISO 4400 (DIN 43650) connector that provides a quick-disconnect electrical interface in field wiring. When that plug is fitted, the enclosure achieves an IP67 rating to resist dust ingress and temporary immersion during wash-downs. The solenoid is rated for a 100 % continuous duty cycle, allowing the valve to remain energized without thermal rest periods. Operating pressure at the P, A, and B ports can reach 350 bar (5000 psi), enabling the valve to control high-pressure circuits.

The body mounts to a subplate using the ISO 4401-AB-03-4-A interface, aligning pressure and service ports with standard manifold patterns. This pattern corresponds to the CETOP 3, or NFPA D03, mounting standard so it interchanges with other size 03 directional valves. Inside the body, spool designation 0 provides an open-center flow path that links all ports in the neutral position to unload the pump. A left-hand end-to-center spring returns the spool to that neutral state when the solenoid is de-energized, ensuring predictable fail-safe positioning. Flow into the pressure port passes through a 1.0 mm orifice which moderates pilot oil and protects the actuator from rapid pressure spikes.
