The DG4S4 012A 440AC 50 50 valve belongs to the DG4 Directional Valves series and is produced by Vickers for directional control in hydraulic automation. It is solenoid operated, so spool movement is triggered electrically rather than mechanically. The coil is rated at 440 VAC 50 Hz, which matches high-voltage industrial supplies, and a flying lead coil simplifies wiring inside confined panels. The housing tolerates system pressures up to 3000 psi while allowing a continuous flow of 20 gpm through the body. An internal 0.047 in orifice meters pilot flow, and Buna-N seals provide compatibility with petroleum-based fluids. The valve bolts to an ISO 4401-05 interface for repeatable alignment with subplates.
For compact installation, the unit is intended for subplate or manifold mounting and presents external dimensions of 9.500 in length, 2.810 in width, and 3.850 in height. There is no manual override, so coil energization is the sole means of shifting the spool. Safe service is defined between ambient temperatures of 20 °C and 50 °C, suiting most machine environments. The design allows the tank port to withstand 1000 psi back-pressure without compromising sealing. These characteristics round out the hydraulic profile of the DG4S4 012A 440AC 50 50 valve, supplying dependable directional control where high system pressure and moderate flow are required.
