The main function of the excavator safety relief valve is to protect the hydraulic system from being damaged by

excessive pressure.Specifically, when the pressure in the hydraulic system exceeds the set value of the safety relief valve,

the safety relief valve will automatically open to release the excess pressure to the outside of the system, thereby avoiding systemoverload and failure. This protects hydraulic components, such as hydraulic pumps, hydraulic cylinders, control valves, etc., from excessive pressure and extends their service life.

In addition, the safety relief valve can also play a role in stabilizing system pressure. Under certain working conditions, such as when excavating heavy-load materials, the system may generate instantaneous high-pressure peaks. The safety relief valve can quickly respond and release these pressure peaks, keeping the system pressure within a stable range and improving the excavator's working efficiency and reliability.

It should be noted that the set pressure of the safety relief valve should be adjusted according to the specific model and working conditions of the excavator to ensure its normal operation and the safety of the protection system. When using an excavator, it is very important to regularly inspect and maintain the safety relief valve to ensure that it performs well and can effectively protect the hydraulic system. If the safety relief valve is found to be faulty or damaged, it should be repaired or replaced in time.
