The DG1V4-133A0-10 valve is a component of the Directional Control Valves series produced by Vickers for hydraulic automation circuits. It is a single stage, D05 size unit that establishes four flow paths to direct pressure and return lines as required. The design provides a nominal flow capability of 30 L/min (8 gpm), enabling moderate throughput in machine tools and power units. Operation is achieved with a manual knob, translating hand input into a 3.6 mm (0.14 in) spool stroke that shifts the internal lands. A spring offset arrangement returns the spool to its rest position when the knob is released, ensuring predictable neutral alignment. Installation follows the ISO 4401-05 (NFPA D05) interface so it bolts directly to matching subplates without additional adapters.
This model mounts on subplate or manifold bases, permitting compact stacking inside hydraulic manifolds. It is intended for use with petroleum oils and maintains performance when the fluid cleanliness level is held at ISO 4406 19/17/14. The pressure rating on the pressure, A, and B ports reaches 315 bar (4500 psi), while the tank port can be subjected to 70 bar (1000 psi), allowing the valve to work in high-pressure systems that also carry back-pressure on return lines. These limits support reliable actuation without undue spool leakage or deformation. By combining the stated pressure capacities with the specified fluid and cleanliness requirements, the DG1V4-133A0-10 offers consistent directional control when integrated into subplate-mounted hydraulic assemblies.
