DG4V52AJMUH620J99

The DG4V52AJMUH620J99 valve belongs to the DG4 Directional Valves series from Vickers and is used to switch hydraulic flow paths in automated machinery. It is solenoid-operated so electrical signals can reposition the spool without manual effort, and the coil runs on 24 V DC under code H to match common control voltages. A coil power rating of 38 W supplies enough magnetic force to move the NG10 spool even under high back-pressure. Continuous duty at 100 % ED allows the energizing circuit to remain on during long machine cycles. The single-stage layout keeps the flow path short for quick response, while spool type 2A in the J design establishes the standard P-A and B-T connections needed for cylinder extension and retraction. Speed control option J99 omits an orifice so the spool shifts at full hydraulic speed when the solenoid is powered. Electrical termination is through an ISO 4400 (DIN 43650) connector, and when the DIN plug is fitted the assembly attains IP65 ingress protection against splashed water and dust. Valve size NG10 (D05) makes the unit suitable for medium-frame manifolds and ensures interchangeability with other D05 components.

The valve operates in ambient temperatures from −20 to +70 °C, permitting use on outdoor equipment and inside warm plant rooms without derating. A maximum flow capacity of 120 L/min (32.0 gpm) supports rapid actuator movements in presses, injection molding machines, and material-handling rigs. Pressure limits of 315 bar (4500 psi) on the P, A, and B ports confirm that the body and spool can withstand high-force tasks, while the tank port is rated to 160 bar (2325 psi) so elevated return-line back-pressures do not compromise operation. The ISO 4401-05 / NFPA D05 mounting interface lets the valve bolt directly to standard subplates, reducing plumbing length and simplifying service swaps. Compatibility with petroleum oils ensures the seals, clearances, and surface finishes resist wear and maintain leakage control when conventional hydraulic fluids are used.
