Vickers Type DG5V-8 Solenoid Valve | DG5S-8-2A | DG5V-8-S-2A | DG5V-8-6C | Pilot Operated NG25 Valve

Vickers DG5S & DG5V-8 Series Pilot-Operated Solenoid Valves

Product Overview: The Vickers DG5 series is a range of two-stage directional valves engineered for extreme heavy-duty and high-flow applications. As the industry standard for Size 25 (NG25 / CETOP 8), the series includes the DG5S (Standard) and DG5V (High Performance) models. By utilizing a precision pilot stage to actuate the main spool, the DG5-8 series provides exceptionally smooth switching control, significantly mitigating the severe hydraulic shock associated with high-pressure, large-flow transitions in massive hydraulic systems.

Featured models include: DG5S-8-2A-M-U-D5-60, DG5V-8-S-2A-M-U-H-10, DG5S-8-6C-M-U-D5-60, and the external drain model DG5V-8-H-6C-T-M-U-D-12.

Key Technical Advantages:

• Superior Flow Management: Designed for high-power hydraulic units, with rated flow capacities reaching up to 700 L/min (depending on spool type), ideal for metallurgy, forging, and heavy shearing equipment.

• Versatile Pilot Configurations: Available in H (High-performance pilot) and S (Standard pilot) specifications, ensuring precise spool movement across various fluid viscosities and pressure environments.

• Flexible Drain Options (T): The T suffix denotes an External Drain configuration, ensuring pilot actuation remains independent of back-pressure in the main tank line for maximum reliability.

• Global Voltage Compatibility: Supports industrial standard voltages such as D5 (230V AC), D (110V AC), and H (24V DC), featuring a manual override (M) for safe commissioning and emergency use.
