The DG3S4 062A 51 valve is produced by Vickers and belongs to the Directional Control Valves series. It directs hydraulic flow in automation circuits that require reliable port switching. The unit is pilot operated, so a low-flow control signal shifts the main spool while the main flow remains separate. The hydraulic path is arranged as a single stage to reduce complexity and keep response time predictable. Internally, Spool 2 geometry defines the port connections, and a spring offset from end to end forces the spool to its rest position when pilot pressure drops. No manual override is fitted, and the design also omits solenoid energizing hardware, so all actuation is hydraulic. The valve mounts on a subplate or manifold for quick replacement, and it withstands system pressures up to 3000 psi (210 bar).
Functionally, the model occupies the directional control category defined for the series. It is compatible with petroleum oils and maintains performance when the fluid cleanliness is held to 20/18/15. Buna-N seals contain the working medium across the full range of operating conditions. The tank port is rated for 3000 psi (210 bar), allowing back pressure without risk of damage. Service temperatures can be as low as 18 °C (0 °F) and as high as 65 °C (150 °F), supporting cold starts and extended warm running in standard machinery.
