Critical System Overload Protection
As the main relief valve, it establishes the maximum pressure limit for the entire hydraulic system. When system pressure exceeds this preset threshold due to heavy loads or sudden shocks, the valve instantly opens to divert excess oil back to the tank. This prevents catastrophic damage to the main pump, control valves, cylinders, and other expensive components.
