Critical System Overload Protection
As the primary safety valve, its core function is to precisely limit the maximum working pressure of the hydraulic system. When system pressure exceeds the preset safe limit due to heavy loads or shocks, the valve opens instantly to return high-pressure oil to the tank. This effectively prevents damage to the main pump, control valves, cylinders, and other expensive components caused by overloading.
