The DG4S4016050 valve belongs to the DG4 Directional Valves series from Vickers and directs hydraulic flow in automated circuits. The unit is solenoid operated, using an electrical actuator to shift the internal spool. Its coil is wound for 115 VAC at 60 Hz, allowing direct connection to common control power. Flying leads provide the coil connection, so the installer can route conductors through rigid or flexible conduit as required. The valve mounts to a manifold that follows the ISO 4401-05 interface, ensuring interchange with standard sub-plates. Inside, a catalog Spool 6 element defines the flow paths available to the connected ports. A spring-centered three-position arrangement returns the spool to neutral when power is removed, supporting fail-safe centering in machinery stops. Under continuous duty the assembly passes up to 20 gpm while containing system pressure to 3000 psi without external leakage.
System fluid supplied to the DG4S4016050 must be filtered so that contamination does not exceed 20/18/15 micron, preserving spool clearances and seal life. All dynamic seals are Buna-N to resist common petroleum-based oils used in industrial hydraulics. The valve operates in ambient or oil temperatures from 20 °C to 50 °C, covering typical plant environments. Physical dimensions measure 12.540 in in length, 2.810 in in width, and 3.850 in in height, which helps designers allocate space on compact manifolds. A separate tank port withstands back-pressure up to 1000 psi, preventing seal extrusion during rapid actuator retraction. Together these ratings establish the mechanical envelope, environmental limits, and cleanliness requirements necessary for reliable directional control in automated hydraulic machinery.
