DG4V3S2AMFPA4WLH560EN476

The DG4V3S2AMFPA4WLH560EN476 directional valve is manufactured by Vickers within the DG4 Directional Valves series and is used to shift hydraulic flow paths in automated machinery. It employs a wet armature solenoid so the energized components remain cooled and isolated from the working fluid. The spool is the closed-center pattern identified as type 2, allowing all ports to be blocked when the valve is centered. A spring offset arrangement designated as code A returns the spool to its rest position when the coil is de-energized. During operation it handles a rated flow of 40 l/min (10.5 US gpm) and withstands system pressures up to 350 bar (5000 psi). Continuous service is possible because the electromagnetic assembly is specified for a 100 percent relative duty factor. Thermal limits are managed by Class F coil encapsulation together with Class H winding insulation, and each coil consumes 30 W to generate the magnetic force required for actuation. Reliable motion control further depends on maintaining oil cleanliness to ISO 4406 level 19/17/14.

Panel integration is based on the ISO 4401-AB-03-4-A mounting interface, which standardizes port geometry and bolt pattern across 03-size components so the valve fits directly onto common subplates without adapter blocks. Four M5-0.8-6H mounting bolts secure the body; this metric size allows the use of standard socket-head screws in manifold blocks. Correct sealing requires the mating surface to be flat within 0.013 mm, a tolerance that limits internal leakage and prevents distortion of the sealing lands. Electrical safety in wash-down environments is provided by an IP67 enclosure when an ISO 4400 plug is fitted, guarding against dust ingress and temporary immersion so field wiring can pass through machine cleaning tunnels. A single-solenoid build weighs 1.6 kg, while the double-solenoid version increases mass to 2.2 kg, information that supports the selection of vibration isolators and robotic tooling when the valve is installed on moving axes.
