DG4V32NMUA660

The DG4V32NMUA660 valve belongs to the DG4 Directional Valves series and is manufactured by Vickers for hydraulic automation that requires electrically prompted flow switching. Actuation is solenoid operated, letting the control system shift the spool without pilot pressure. A coil rating of 110 VAC at 50 Hz allows it to be wired straight to many international mains supplies, while power consumption of 54 VA defines the load drawn from the control transformer. Connection to the harness is made through an ISO 4400 (DIN 43650) connector so field replacement can be performed with a single screw. The unit mounts on an ISO 4401-03 pattern, giving compatibility with common sub-plates. Internal porting follows spool type 2, producing the designated open and blocked passages when energized. For service personnel, a plain manual override is provided to shift the spool during startup checks or in the event of electrical failure. There is no indicator light and no spool position monitor, keeping the envelope small and eliminating extra wiring.

The hydraulic section supports a rated pressure of 350 bar so the valve can be installed in high-pressure circuits without derating. Maximum flow is 80 L/min, which establishes the capacity when sizing pumps and actuators in the same loop. Petroleum oils are the approved operating fluid, and cleanliness must be held to ISO 4406 class 19/17/14 to prevent abrasive wear on the lands and body. Overall dimensions influence manifold layout: length is 5.750 in, width is 1.880 in, and height is 3.420 in, allowing the designer to confirm clearance inside cramped power units. These geometric values also help determine stacking distances when multiple DG4V32NMUA660 valves share a common bar manifold. The absence of supplemental indicator hardware and the specified pressure-flow limits together define a compact, electrically actuated valve suitable for disciplined hydraulic circuits.
