7 OCEAN Hydraulic Valve DSV-G02 DSD-G03 | DSV-G02-2C-A220-20 | Solenoid Valve

LIC Hydraulic proudly offers the 7 OCEAN DSV & DSD Series, a high-performance range of solenoid-operated directional control valves. Utilizing wet-type solenoid technology, these valves immerse the moving plunger in hydraulic oil, ensuring superior heat dissipation, lubrication, and whisper-quiet operation. The DSV-G02-2C-A220-20 is the industry standard for NG6 (Size 6) mounting, offering consistent performance at pressures up to $315\text{ bar}$.

Technical Specifications (Quick Reference)

• Series: DSV (Standard) / DSD (Heavy Duty).

• Mounting: ISO 4401-03 (NG6) and ISO 4401-05 (NG10).

• Max Pressure: $315\text{ bar}$ ($4500\text{ PSI}$).

• Voltage Options: AC110V, AC220V, DC12V, DC24V.

• Ingress Protection: IP65 with DIN 43650 connectors.

Key Technical Advantages

• Wet-Solenoid Reliability: Friction-free plunger movement extends the operational life and provides smoother shifting compared to dry-solenoid designs.

• Minimized Pressure Drop: Strategically cast internal galleries reduce flow resistance, maximizing your hydraulic system’s power output.

• Modular Versatility: Compatible with standard subplates and sandwich-mounted modular valves (Stack valves) for complex circuit integration.

• Robust Electrical Design: High-duty cycle coils designed to withstand voltage fluctuations in industrial environments.

Application Areas

• Plastics Machinery: Injection molding and blow molding control.

• Machine Tools: Clamping, pallet changing, and turret indexing.

• General Industry: Power units for lifts, presses, and material handling systems.

Expert Maintenance Tips

• Coil Safety: Never energize the solenoid coil unless it is properly mounted on the valve tube.

• O-Ring Placement: During installation, ensure the standard O-rings are correctly seated in the bottom ports. Misalignment is the leading cause of external leaks.

• Filter Integrity: Maintain oil cleanliness at ISO 4406 19/17/14. Silt accumulation around the spool can lead to sluggish response or valve “sticking.”
