Comprehensive Overload Protection
-
As the main relief valve, it limits the maximum working pressure of the hydraulic system.
-
When pressure rises abnormally, the valve opens instantly to release excess oil back to the tank.
-
This prevents costly damage to the main pump, control valves, cylinders, and other core components.
