7Ocean DSV Series Directional Valve | DSV-G02-2C-A220-20 | DSV-G03-2B3-DC24-82

The 7Ocean DSV Series from LIC Hydraulic is a premium line of solenoid-operated directional spool valves. Models like the DSV-G02-2C-A220-20 and DSV-G03-2B3-DC24-82 are built to meet the rigorous demands of industrial automation. Utilizing wet-pin solenoid technology, these valves provide smooth switching, low operational noise, and an extended duty cycle by using the hydraulic fluid to dissipate heat and cushion the armature movement. We provide 100% drop-in replacements for original 7Ocean units, ensuring full compatibility with CETOP 03 (NG6) and CETOP 05 (NG10) mounting patterns.

Technical Highlights

• Frame Sizes: G02 (NG6) and G03 (NG10).

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

• Max Flow Rate: G02 up to $80\text{ L/min}$; G03 up to $120\text{ L/min}$.

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

• Protection: IP65 rated molded coils.

Core Advantages

• Reduced Pressure Drop: Optimized internal galleries ensure maximum efficiency by minimizing energy loss and oil overheating during flow transitions.

• Superior Coil Durability: The molded coil design offers excellent thermal dissipation and resistance to moisture and dust, ensuring long-term reliability in harsh environments.

• Fast Response Times: Precision-engineered spools and high-force solenoids allow for rapid switching cycles, essential for high-speed CNC and injection molding machines.

• Ease of Maintenance: The plug-in coil design allows for quick coil replacement without breaking into the hydraulic circuit, minimizing downtime.

Application Areas

• Plastic Processing: Core pulling and ejector movements in injection molding machines.

• CNC Machine Tools: Hydraulic clamping, turret indexing, and pallet changing.

• Woodworking & Packaging: Automated sorting, cutting, and conveying systems.

• Industrial Power Packs: Primary directional control for standard HPU circuits.

Expert Maintenance Tips

• Coil Protection: For AC solenoids, ensure the spool is never mechanically blocked. If the spool cannot reach its end position, the coil will draw excessive current and burn out within minutes.

• Filter Maintenance: Maintain fluid cleanliness at ISO 18/16/13. Particle contamination is the #1 cause of “spool-sticking” in directional valves.

• Mounting Torque: When installing onto a subplate, follow the specified torque for mounting bolts to prevent valve body distortion, which can lead to internal leakage or spool binding.
