DG4V52NMUEK620

The DG4V52NMUEK620 directional valve is produced by Vickers as part of the DG4 Directional Valves series. It directs hydraulic flow in automated machinery and is actuated by a solenoid, allowing electrical signals to shift the spool without manual intervention. A coil rated at 115 VAC, 60 Hz matches standard North American control power and energizes the solenoid rapidly. An ISO 4400 (DIN 43650) connector simplifies field wiring and permits quick coil replacement during maintenance. The valve mounts on an ISO 4401-05/NFPA D05 interface, so it can be bolted to common sub-plates or manifold stacks. Circuit designers can rely on a maximum operating pressure of 315 bar, enabling use in high-pressure hydraulic systems. The internal passages support a maximum flow of 120 L/min, providing adequate capacity for medium-size actuators. A plain manual override is included to permit spool shifting during commissioning or in the event of power loss.

The valve is intended for petroleum-based hydraulic oils and therefore fits most industrial power units without fluid conversion. System cleanliness should be maintained at ISO code 19/17/14 to protect the spool and reduce leakage. During operation the coil draws 130 VA, an important figure when sizing control transformers or relay outputs. An enclosure height of 4.530 in, length of 9.680 in, and width of 2.800 in define the clearance needed inside a manifold bank or machine frame. No indicator light is fitted, so status feedback must be provided by the control circuit rather than the valve body. The absence of auxiliary lights helps keep envelope size small. Together these physical and electrical characteristics let the valve deliver reliable directional control in automated hydraulic equipment while remaining compatible with standard mounting, power supply, and cleanliness practices.
