The DG4V-3S-0B-M-U-B5-60 directional valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation circuits that require reliable on-off flow control. It uses a DC solenoid rated at 30 W to shift the spool, so panel designers can size power supplies accordingly. The solenoid operates continuously because the duty factor is 100 percent ED, which avoids cooling pauses in cyclic machines. Class F coil encapsulation protects the windings from vibration and moisture, while Class H insulation tolerates elevated winding temperatures during prolonged energization. Electrical connection is provided through an ISO 4400 (DIN 43650) connector, allowing quick field replacement without rewiring. The coil draws consistently when the applied voltage remains at least 90 percent of its rating, ensuring positive spool movement even during supply dips. An IP67 enclosure keeps dust and temporary water immersion from reaching internal components, supporting outdoor or wash-down installations.
Hydraulically, the valve mounts to an ISO 4401-AB-03-4-A subplate and matches the CETOP 3 / NFPA D03 interface, which lets it replace common size 3 valves without manifold modifications. With a maximum flow capacity of 40 l/min (10.5 US gpm), it suits medium-duty actuator circuits, and the pressure rating of 350 bar (5000 psi) on ports P, A, and B accommodates high-pressure pumps. The spool is the open-center type 0, so system flow returns to tank when the solenoid is de-energized, preventing heat buildup at idle. A spring offset from end to center, designated arrangement B, automatically shifts the spool back to its neutral position when power is removed, providing fail-safe operation. The valve measures 219.4 mm (8.64 in) in overall length, which helps define stack height in multi-valve manifolds, and the single-solenoid version weighs 1.6 kg (3.5 lb), light enough for direct mounting on mobile equipment frames.
