DG4V-3S-2A-M-U-B5-60

The DG4V-3S-2A-M-U-B5-60 valve belongs to the DG4 Directional Valves series from Vickers and is used to route hydraulic fluid in automated machinery. Its spool is designated as type 2, so all ports are blocked in the centered position to hold actuators at rest. The spring arrangement coded A offsets the spool to an end position when the solenoid is de-energized, providing fail-safe return without external force. During operation it can pass up to 40 l/min (10.5 US gpm), enabling moderate flow circuits. Ports P, A, and B withstand pressures up to 350 bar (5000 psi), while the T port is limited to 100 bar (1450 psi), matching common tank line requirements. The solenoid consumes 30 W, which simplifies power budgeting in control panels. Continuous duty rated at 100 % ED means the coil may remain energized without cooldown cycles. The winding uses Class H insulation for high thermal endurance, and the encapsulation is Class F to protect the coil and extend service life. Electrical termination is via an ISO 4400 (DIN 43650) connector that offers quick plug-in installation.

An IP67 enclosure rating is achieved when the mating plug is fitted, so the envelope resists dust ingress and temporary immersion during field servicing. A plain manual override located at the solenoid end lets technicians shift the spool without electrical power for setup or fault recovery. The valve mounts to subplates or manifolds following the ISO 4401-AB-03-4-A pattern, which aligns with CETOP 3 and NFPA D03 standards for interchangeability. Four mounting screws with #10-24 UNC threads secure the body, ensuring uniform clamping to prevent leakage. Overall length measures 219.4 mm (8.64 in), so the unit fits compactly within machine envelopes. A single-solenoid configuration weighs 1.6 kg (3.5 lb), allowing manual handling during maintenance. The coil housing and body are sealed to maintain the previously noted IP rating even when the valve is installed in spray zones. These mechanical and environmental features integrate with the flow and pressure capabilities described earlier to support reliable directional control in hydraulic automation systems.
