Vickers DG5V Series Pilot-Operated Directional Valves

Product Overview: The Vickers DG4V series by Eaton features high-performance, two-stage hydraulic directional valves. The assembly consists of a small pilot solenoid valve (typically a DG4V-3) mounted on a high-flow main stage. These valves are specifically engineered for industrial applications requiring massive flow capacities and high-pressure switching. By using pilot pressure to actuate the main spool, the DG5V series controls substantial hydraulic power with minimal electrical input, making it indispensable for large forging presses, heavy machine tools, and large-scale power units.

Featured models: DG5V-5-2N-T-M-U-H7-10, DG5V-8-H-8C-E-VM-U-H-10, and DG5V-8-H-2C-E-M-U-H-10.

Key Technical Advantages:

• Massive Flow Management: The DG5V-8 (NG25) models support flow rates up to 700 L/min (185 USgpm), while the DG5V-5 (NG10) bridges the gap for medium-to-high flow requirements.

• Flexible Pilot/Drain Configurations: Supports Internal or External pilot pressure and drain options, identified by “E” or “T” suffixes to precisely match system circuit logic.

• Smooth Shifting & Low Shock: The two-stage design allows for fine-tuning of the main spool shifting speed (via optional choke blocks), effectively neutralizing hydraulic water hammer.

• Rugged High-Pressure Build: Rated for operating pressures up to 31.5 MPa (315 bar), featuring U (DIN) connectors with IP65 environmental protection.
