Pressure relief valve for Demag AC80-1

The pressure relief valve, part number 410 675 12, serves as a safety component within the hydraulic system of the Demag AC80-1 crane. Its primary function is to monitor system pressure and prevent spikes that could potentially compromise the structural integrity of hydraulic pumps, cylinders, and hoses. When the internal pressure exceeds the specified threshold, the valve opens to redirect excess hydraulic fluid back to the reservoir, ensuring the system remains within its designated operating limits.

This component is engineered specifically for the Demag AC80-1 model. By maintaining consistent pressure levels, the valve protects the hydraulic circuit from overloads during operation. Pressure relief valves are standard in heavy machinery hydraulic systems to regulate flow and pressure, serving as a safeguard for the entire circuit by diverting fluid whenever pressure levels surpass the rated capacity of the system components.
