Vickers Type DG Directional Valve | DG17V-3 | DG21V-3 | DG17V4 | NG6 NG10 Hydraulic Control Valve

DG Series Industrial Hydraulic Directional Control Valves

Product Overview: The Vickers DG series stands as a benchmark in industrial hydraulics, fully compliant with ISO 4401 mounting standards. This range covers diverse configurations from the manually operated DG17 to the solenoid/pilot-actuated DG21, providing precise fluid guidance for complex automated circuits. The valve bodies are cast from high-strength materials with surface-hardened internal galleries, significantly enhancing wear resistance and minimizing internal leakage to ensure superior switching accuracy over millions of cycles.

Featured models include: DG17V-3-2C-60, DG17V-3-6C-60, DG17V4-012C-10, DG21V-3-2AL-2-60, and DG21V-3-OA-2-60.

Key Technical Advantages:

• Versatile Actuation Options: Features DG17 (Lever/Manual operation) and DG21 (Pilot-operated or electronic control), catering to everything from simple manual equipment to high-end CNC machinery.

• Classic Design Series (60/10): Covers the field-proven 60 and 10 design series, ensuring high interchangeability with existing legacy systems.

• Low Pressure Drop & High Flow: Optimized spool geometry significantly reduces energy loss and hydraulic shocks during switching.

• High-Response Spool Logic: Includes 2C (3-pos, closed center), 6C (Unloading center), and OA (Open functionality) configurations for rapid response and accurate positioning.
