Danfoss Eaton Vickers Two-Stage Pilot-Operated Solenoid Relief/Unloading Valve CG5V-8GW-D-M-U-H7-11 859553
Application Scenarios
1. Die-casting and Injection Molding Machines: During the pressure-holding or cooling/waiting phases, the control system uses electrical signals to rapidly switch the system to a low-pressure, no-load unloading state, thereby significantly reducing hydraulic oil temperature and motor energy consumption.
2. Heavy-duty Hydraulic Presses and Stamping Machines: Serves as a core safety pressure-limiting valve in the main circuit, providing overpressure protection and enabling low-pressure circulation during the rapid, no-load return stroke of the slide.
3. Heavy-duty Machine Tools and Steel Mill Automation: Utilized in large-scale industrial hydraulic power units to regulate the maximum system pressure during transitions between fixture clamping and the stationary state of various actuators.
4. Marine and Deck Machinery: Employed in hydraulic systems for marine anchor windlasses, winches, cranes, and steering gear; it handles sudden overload shocks in harsh environments to ensure pipeline safety.
Routine Maintenance & Wear Parts (Seal & Coil Kits)
| BOM ID | Part Name | Core Specifications / OEM Cross-Ref | Qty | Failure Match & Functional Description |
|---|---|---|---|---|
| BOM-01 | Solenoid Coil | 02-178121 (24V DC / 30W / DIN 43650) |
1 pc | Coil burnout/open circuit. Replace this first if the PLC outputs 24V but the solenoid valve fails to actuate (fails to vent or build pressure). |
