DG4V3S56BLMUHL760EN490

The DG4V3S56BLMUHL760EN490 valve is part of the DG4 Directional Valves series manufactured by Vickers for hydraulic automation where accurate path switching is required. A wet armature solenoid isolates moving parts from external contamination and is supported by Class F coil encapsulation that tolerates elevated winding temperatures. The coil operates from a 24 V DC supply and consumes 30 W, delivering the magnetic force needed to shift the internal spool. Continuous energization is permissible because the duty cycle is rated at 100 % ED, avoiding thermal overload in holding conditions. Dynamic behavior is defined by a 60 ms energize time and a 40 ms de-energize time, ensuring predictable response in proportional or on/off circuits. Power is routed through an ISO 4400 (DIN 43650) connector that simplifies field wiring, and the spool coded "56" directs ports A and B to tank while blocking P and providing regenerative flow to A during actuation.

The valve accommodates a maximum flow of 40 l/min (10.5 gpm), enabling it to serve moderate-capacity mobile and industrial manifolds. Working ports P, A, and B withstand pressures up to 350 bar (5000 psi), while the tank return line is limited to 210 bar (3000 psi), ensuring safe operation within typical system limits. A mounting interface conforming to ISO 4401-AB-03-4-A, also referenced as CETOP 3 or NFPA D03, lets the unit bolt directly to standard subplates without adapters. When a mating plug is installed, the enclosure reaches an IP67 ingress rating, providing resistance to dust and temporary immersion common in outdoor machinery. Overall mass is kept to 1.6 kg (3.5 lb) for the single-solenoid configuration, allowing easy handling during assembly or service. These characteristics collectively allow the DG4V3S56BLMUHL760EN490 to deliver reliable, space-efficient directional control in high-pressure hydraulic systems.
