Critical Overload Protection
As the main relief valve, it protects the entire hydraulic system by limiting maximum pressure. When system pressure exceeds the preset limit, the valve instantly opens to divert excess oil back to the tank, preventing catastrophic damage to the main pump, control valves, cylinders, and other expensive components. A failed main relief valve affects all hydraulic functions simultaneously and is the first valve to suspect when system-wide low pressure is confirmed.
