🛠️ Product Description

Relief Valve is a critical hydraulic safety component used in the Volvo EC480 excavator. It is designed to control and limit hydraulic system pressure, protecting major components like pumps, cylinders, and control valves from damage due to overpressure.

⚙️ Function / Working

• Monitors hydraulic pressure in the system
• When pressure exceeds the preset limit, the valve opens automatically
• Diverts excess oil back to the hydraulic tank
• Maintains safe and stable operating pressure

👉 Prevents system failure and ensures smooth machine operation.
