 Key attributes

Comprehensive System 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, avoiding expensive repair costs.
