The DG4S4U 016C W2 B 53UG valve belongs to the DG4 Directional Valves series from Vickers and is intended for hydraulic automation where controlled flow direction is needed. The unit is solenoid operated, allowing electrical actuation of the spool. It is built as a single-stage assembly and employs Spool 6 to establish its flow paths. The coil is rated for 110 V AC at 50 Hz and 120 V AC at 60 Hz, and it reaches a stable magnetic force within an energize time of 20 to 40 ms. Subplate or manifold mounting simplifies installation, while the interface follows the ISO 4401-05 (D05) pattern for interchangeability with standard bases. The valve handles petroleum oils as the working medium, aligning with common industrial hydraulic fluids.
The maximum operating pressure at the service ports is 3000 psi, and the design supports a continuous flow up to 20 gpm without exceeding performance limits. The tank port is rated for 1000 psi to prevent back-pressure damage during return flow. Internal passages include a 0.047-inch orifice that manages pilot oil movement and damping. Sealing is provided by Buna-N material to maintain containment of the hydraulic fluid. A spring-centered three-position arrangement returns the spool to neutral when the solenoid is de-energized, ensuring predictable fail-safe positioning. Electrical connection is made through a wiring housing, protecting the coil leads from contamination and mechanical strain.
