Critical System Overload Protection
The primary function of these valves is to limit the maximum hydraulic system pressure. When system pressure exceeds the preset safe limit due to heavy loads or sudden shocks, the valve opens instantly to relieve excess pressure back to the tank. This effectively prevents damage to the main pump, cylinders, control valves, and hydraulic lines – protecting expensive components from costly failures.
