The DG4V-3S-6C-Z-M-KUP5D2-G5-60-EN146 directional valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation where electrical actuation selects fluid paths. Its 12 VDC coil voltage lets the valve interface with common mobile or battery-supplied controllers, while a 30 W coil power rating defines the steady electrical demand placed on the driver. The coil is molded to Class F standards so the encapsulation tolerates elevated winding temperatures, and the internal copper is insulated to Class H so prolonged heat cycles do not degrade performance. A 100 percent duty cycle permits the solenoid to stay energized continuously without thermal derating. Wiring leaves the housing through a top-exit flying lead set, simplifying routing along machine frames. An encapsulated diode is installed across the winding to suppress voltage spikes when the coil is switched off, protecting sensitive electronics upstream. With both solenoids fitted, the assembly weighs 2.2 kg (4.8 lb), allowing single-hand placement during manifold service.
A P blocked, A and B to T center condition keeps pump flow isolated and vents both work ports to tank when the spool returns to neutral, providing safe standby control. The valve passes up to 40 l/min (10.5 US gpm), matching the needs of medium flow circuits, and sustains working pressures to 350 bar (5000 psi) so it can be placed in high-pressure lines. The tank port is limited to 100 bar (1450 psi), setting a back-pressure ceiling for return plumbing. Installation follows the ISO 4401-AB-03-4-A pattern, making the unit interchangeable with other size 03 sub-plate devices. Mounting bolts may be either M5-0.8-6H or 10-24 UNC-2B, giving flexibility between metric and imperial hardware. A mounting surface flatness tolerance of 0.013 mm ensures the seal between valve and manifold remains leak-free. Fluid entering the valve must meet ISO 4406 19/17/14 cleanliness, which limits particulate contamination and prolongs spool life.
