• Function

1.Pressure Overload Protection: The primary role of the relief valve is to monitor system pressure. When pressure exceeds a pre-set safe threshold (determined by the valve’s design and calibration), the valve automatically opens to release excess fluid or gas. This prevents damage to sensitive components like hoses, pumps, cylinders, or pipes that could fail under extreme pressure, avoiding costly breakdowns or safety hazards.

2.System Pressure Regulation: Beyond safety, the valve helps maintain stable operating pressure within the system. By releasing only the excess pressure, it ensures pressure stays within the optimal range required for equipment performance. This is crucial for consistent operation of hydraulic tools (e.g., excavator arms, loader buckets) or fluid circuits, where precise pressure control directly impacts functionality.
