The DG4V52ALJMUH620 valve belongs to the DG4 Directional Valves series manufactured by Vickers. Designed for hydraulic automation, it directs oil flow by shifting an internal spool under solenoid force. The assembly uses a single wet armature solenoid rated at 24 V DC and 1.58 A, so control cabinets can power it directly from a logic-level supply. A type 2 closed-center spool is installed, and a spring offset on the left-hand side returns the spool when the coil is not energized. The device provides two discrete positions to open or block ports, a push-pin manual override permits local actuation, and the two-position construction keeps switching time low for responsive circuit control.
Operating limits include a maximum system pressure of 31.5 MPa and an allowable T-port back pressure of 15.7 MPa, ensuring compatibility with high-pressure circuits. The unit mounts on a subplate through the ISO 4401-AC-05-4-A interface and is secured with four M6 × 40 bolts, streamlining replacement in standardized manifolds. Electrical connection is made via a DIN 43650 connector for quick coil changes, and Class H insulation keeps winding temperatures safe up to 180 °C during continuous duty. This combination of robust pressure capacity, standardized mounting, and straightforward wiring supports dependable operation in presses, plastic injection machines, and other automated hydraulic equipment.
