Vickers DG4V Series Solenoid Valve | DG4V-3 DG4V-5 | DG4V-5-6CJ-M-U-H7-29

LIC Hydraulic is a specialized provider of Vickers DG4V Series Solenoid Valves, the gold standard for high-performance fluid control. Available in Size 3 (DG4V-3) and Size 5 (DG4V-5), these direct-operated spool valves are designed to minimize flow resistance and maximize system reliability. Models like the DG4V-5-6CJ-M-U-H7-29-EN124 are engineered for rigorous industrial duty, featuring wet-pin solenoids that provide smooth shifting and exceptional service life under pressures up to $315\text{ bar}$. Vickers DG4V technology ensures your hydraulic systems operate with maximum efficiency and precision.

Technical Specifications (Bulleted List)

• Frame Sizes: NG6 (Size 3) and NG10 (Size 5).

• Max Pressure: $315\text{ bar}$ ($4500\text{ PSI}$) at P, A, and B ports; $120\text{ bar}$ at T port.

• Flow Capacity: DG4V-5 supports high flow rates up to $160\text{ L/min}$ (depending on spool).

• Solenoid Type: Wet-armature, oil-immersed for superior heat dissipation.

• Mounting Interface: Compliant with ISO 4401-03 (Size 3) and ISO 4401-05 (Size 5).

• Electrical Connection: DIN 43650 (U-type), M12, or lead-wire options.

Key Technical Advantages

• Reduced Power Consumption: Highly optimized internal fluid galleries significantly lower pressure drops, translating to lower operational costs.

• Robust Manual Overrides: Equipped with rugged manual push-pins as standard, allowing for manual machine cycling during setup or power outages.

• Thermal Resilient Coils: The H7 series high-performance coils are designed to operate at $100\%$ duty cycle even in ambient temperatures up to $70\text{°C}$.

• Dynamic Sealing Integrity: The wet-pin design eliminates the need for dynamic shaft seals at the armature, effectively preventing external leaks common in dry-pin solenoid valves.

Application Areas

• Metal Forming: Precision sequencing for hydraulic presses and stamping machines.

• Industrial HPUs: Primary directional control for stationary hydraulic power units in manufacturing.

• Marine & Offshore: Corrosion-resistant options for deck machinery and hatch control.

Expert Maintenance Tips

• Filtration Integrity: The precision-ground spools of the DG4V-5 require an oil cleanliness level of $ISO\text{ 18/16/14}$. Contaminants can lead to spool “silting” or jamming.

• Solenoid Orientation: For two-position valves, horizontal mounting is preferred to prevent uneven wear on the spool caused by gravity.

• Connector Sealing: Ensure the DIN connector gaskets are intact. Moisture ingress into the U-type connection is the most common cause of coil failure in wash-down environments.
