Key functions

1.It limits the maximum pressure of the hydraulic circuit. When system pressure exceeds the preset value, the valve opens automatically to divert excess hydraulic oil back to the tank, preventing overpressure damage to pumps, cylinders and hydraulic pipes.

2.It stabilizes the working pressure of the hydraulic system and keeps the machine operating within the designed pressure range.

3.It acts as a safety protection component to avoid system overload during heavy load or sudden stall conditions.
