The DG4M4-32C-20-JA directional control valve belongs to the DG4 Directional Valves series and is produced by Vickers for hydraulic automation that requires reliable flow direction under electrical command. It is solenoid operated so current through the coil shifts the spool without the need for pilot pressure, and a wet armature layout submerges magnetic parts in oil to reduce wear. The spool is spring centered in a three-position arrangement that returns ports to neutral when neither coil is powered. Class F coil insulation allows winding temperatures up to 155 °C during continuous duty. The housing tolerates working pressures to 21 MPa, and the tank port accepts back pressure to 7 MPa without affecting spool stability.
Subplate or manifold mounting makes installation simple, while a gasket mounting interface seals the hydraulic ports against leakage. The double-solenoid assembly weighs 1.2 kg, permitting easy handling during maintenance. When powered by an AC source it can switch up to 500 cycles per minute, and the limit drops to 400 cycles per minute on a DC supply for sustained cycling. A voltage tolerance of ±10 % keeps performance consistent despite line variations. Classified as a directional control valve, it integrates into manifolds to select flow paths at high speed in presses, machine tools, and other automated equipment.
