DG4V3S2BMFWB560

The DG4V3S2BMFWB560 valve belongs to the DG4 Directional Valves series and is produced by Vickers for hydraulic automation circuits where rapid flow direction changes are required. It uses solenoid actuation so the spool can be shifted electrically rather than mechanically. The size code D03 matches the ISO 4401-03 mounting interface, allowing direct installation on standardized subplates in compact manifold blocks. A spring-offset end-to-center spool arrangement returns the spool to a defined neutral position when the coil is de-energized, ensuring predictable fail-safe flow paths. The solenoid is positioned at the A port end, which simplifies wiring and service access in stacked valve banks. Maximum working pressure is 350 bar, enabling the unit to handle high-pressure industrial systems without external pressure reducers. The valve is intended for petroleum oils, so standard mineral-based hydraulic fluids can be used without additive changes. There is no manual override, preventing unauthorized hand actuation in safety-critical machinery.

Power is supplied to the coil at 110 VAC 50 Hz or 120 VAC 60 Hz, supporting common single-phase control voltages in North American and international plants. A 1/2-inch NPT conduit box serves as the electrical connection, giving a sealed entry point for armored cable in wash-down environments. The gauge port uses a 7/16-20 UNF SAE thread so standard diagnostic pressure transducers can be attached without adapters. Buna-N seals are fitted to resist swelling when exposed to petroleum oils at elevated temperatures. The valve weighs 3.5 lb, allowing single-hand assembly onto manifold surfaces without lifting equipment. Physical dimensions of 5.75 in length, 1.8 in width, and 3.57 in height keep stack height low and promote tight packing inside control cabinets. These electrical, mechanical, and sealing features support reliable, space-efficient control of actuator direction in presses, machine tools, and mobile hydraulic equipment.
