DG4V4012NMUB510

The DG4V4012NMUB510 valve belongs to the DG4 Directional Valves series and is produced by Vickers for hydraulic automation that requires reliable flow path selection. It is a solenoid-operated unit, so electrical signals energize the coil to shift the spool instead of pilot pressure. The coil accepts 110 VAC at 50 Hz or 120 VAC at 60 Hz, allowing direct connection to standard facility power supplies without transformers. An ISO 4400 (DIN 43650) connector is provided for the electrical interface, simplifying field wiring and ensuring consistent sealing. Plain manual override hardware permits the operator to reposition the spool during commissioning or in case of power loss. There is no indicator light, meaning status feedback must be obtained from a controller or pressure switch. The valve mounts on an ISO 4401-05 / NFPA D05 sub-plate, which standardizes port geometry across manifold blocks. During operation it draws 37 W, and the 22 ms energizing time supports responsive machine cycles.

Rated hydraulic capacity is 115 L/min (30 GPM), so the DG4V4012NMUB510 can handle moderate system flow without excessive pressure drop. The maximum operating pressure of 315 bar (4500 psi) lets it work in high-pressure circuits common to industrial presses and injection equipment. It is intended for petroleum-based oils, ensuring seal compatibility and predictable viscosity behavior across typical temperature ranges. Required fluid cleanliness is coded at 20/18/15 per ISO 4406, which reduces spool wear and prevents sticking. Physical dimensions support compact manifold layouts; overall length is 9.380 in (238.252 mm), height is 4.310 in, and width is 2.840 in (72.136 mm). These measurements help designers confirm envelope clearance inside power units and machine frames. Together the flow rating, pressure limit, fluid requirements, and size data define the operating window so the valve can be applied confidently in automated hydraulic lines.
