The DG4V52AJMUH722 valve is produced by Vickers in the DG4 Directional Valves series. It directs hydraulic oil to actuators in automated systems. The unit is solenoid operated so the spool shifts when an electromagnetic coil is energized. That coil runs on 24 VDC and draws 38 W, which defines the control power requirement. Solenoid energization complies with ANSI B93.9, ensuring compatibility with industry-standard drives. Electrical connection is made through a DIN 43650 (ISO 4400) plug, enabling quick replacement. A plain manual override lets maintenance personnel move the spool without electrical power. The valve attaches to an ISO 4401-05 mounting surface for easy interchange. Overall length is 8.460 in, width is 2.800 in, and height is 4.590 in, dimensions that assist with manifold layout.
Maximum flow capacity is 120 L/min (32 US gpm), so the valve can transmit the rated volume without excessive pressure loss. It withstands operating pressures up to 315 bar (4500 psi), matching requirements for high-pressure hydraulic circuits. Petroleum oils are the specified working fluid, and cleanliness must be maintained at ISO 4406 19/17/14 to prevent wear and sticking. These service limits, combined with the dimensional and electrical parameters described above, define the valve’s role as a reliable directional control element in hydraulic automation.
