The DG4S4L 016C 230 50 50 AU01 valve belongs to the DG4 Directional Valves series produced by Vickers for hydraulic automation that requires reliable flow reversal. This model relies on solenoid-operated actuation so a control signal can move the spool electrically, and the energize time of 20–40 ms minimizes delay between command and shift. A spring-centered, three-position arrangement returns the spool to neutral when power is removed, while spool type 6 defines the functional flow paths used in machinery circuits. The single-stage design limits internal complexity and keeps pressure loss low. A maximum operating pressure of 3000 psi (210 bar) lets the unit work in high-pressure systems, and a maximum flow rate of 20.0 gpm (75.7 L/min) supports medium-capacity actuators. Because there is no manual override, every shift occurs through the electrical input, preventing unplanned hand operation in automated environments.
This valve mounts on a subplate or manifold, and the ISO 4401-05 (NFPA D05) interface aligns its ports so it can be swapped with other standard bases. The unit is intended for use with petroleum oils, and Buna-N seals are fitted to resist swelling and leakage with that fluid. A cleanliness level of 20/18/15 must be maintained to avoid abrasive damage to the spool lands. The tank port withstands back pressure up to 1000 psi (70 bar), allowing the return line to share auxiliary functions without exceeding housing limits. Continuous service is acceptable between 20 °C and 50 °C, so reservoir temperature must stay within this range to preserve seal life, maintain viscosity, and keep the product operating within its specified duty profile.
