DG4S4-013C-50

The DG4S4-013C-50 valve belongs to the DG4 Directional Valves series from Vickers and is intended to shift hydraulic flow paths in automated circuits. A solenoid-operated actuation system converts electrical signals to mechanical movement, enabling remote switching without manual intervention. The unit is built as a single-stage device, so flow changes occur directly across one spool for fast response. A pressure rating of 207 bar (3000 psi) permits use in medium-pressure power units common on industrial machinery. The rated flow of 75.7 L/min matches pumps found on presses and machine tools, letting the valve pass the full system volume without excessive pressure drop. Mounting follows ISO4401-AC-05-4-A / NFPA D05 patterns, ensuring interchangeability with standard subplates. Because the valve is intended for subplate or manifold mounting, installation requires no pipework and keeps maintenance localized. Petroleum-based hydraulic oils are specified as the working fluid, simplifying compatibility with widely used mineral oil systems. A gray iron body resists shock loads while providing the machining accuracy needed for spool bores.

The electrical coil draws 35 W, so control cabinets can size power supplies and heat dissipation accordingly. Power enters through flying leads terminated on an integral block, giving technicians a straightforward wiring point without additional connectors. A Buna-N seal set contains the working fluid and withstands typical petroleum oil additives, guarding against external leakage. When electrical power is unavailable, a plain manual override lets operators shift the spool with a simple mechanical push, aiding setup or emergency operation. Overall length is 9.5 in, width is 2.81 in, and height is 3.85 in; these dimensions help designers allocate manifold space in compact machinery. The assembled weight of 10.3 lb can be supported by standard D05 subplates without reinforcement, making field replacement practical for one person. These features collectively enable reliable directional control in automated hydraulic equipment while minimizing installation complexity.
