Vickers DG4V-5 & DG5V-8 Solenoid Valve | DG4V-5-2CJ | DG5V-8-H-8C | NG10 & NG22 Directional Valve

DG4V-5 & DG5V-8 Series Industrial Solenoid Valves

Product Overview: This series features the direct-acting DG4V-5 (NG10) and the pilot-operated DG5V-8 (NG22) high-performance solenoid directional valves. The DG4V-5 series is renowned for its compact design and high-frequency stability, with “J” designated models (e.g., 2CJ, 6CJ) specifically optimized for the high-vibration environments of injection molding machines. The DG5V-8 series utilizes a pilot stage to ensure smooth shifting in high-pressure, high-flow (up to 700 L/min) applications. Optional VM (Voltage Monitoring) functionality provides an extra layer of electrical protection for precision automation systems.

Featured models: DG5V-8-H-8C-E-VM-U-D-10, DG4V-5-6CJ-M-U-H6-20, DG4V-5-2AJ-M-U-H6-20, and DG4V-5-2CJ-M-U-H6-20.

Key Technical Advantages:

• High-Flow Capacity: The DG5V-8 pilot-operated design ensures minimal hydraulic shock even at large nominal diameters (NG22).

• J-Type Vibration Resistance: DG4V-5-6CJ/2CJ are reinforced for fast-cycling operations, featuring high-precision spool fit and excellent fatigue resistance.

• VM Electrical Protection: The DG5V-8-VM model includes integrated voltage monitoring to prevent malfunctions or coil damage caused by power fluctuations.

• Wet-Pin Solenoid Design: Armatures are immersed in hydraulic fluid for superior cooling, supporting a 100% Duty Cycle (ED).
