Which component is essential for preventing pressure overload in a hydraulic system?

The pressure relief valve is essential for preventing pressure overload in a hydraulic system because it serves as a safety device that protects the system from excessive pressure buildup. When the pressure in the system exceeds a predetermined limit, the pressure relief valve opens to allow fluid to escape, thereby reducing pressure and preventing potential damage to other components, such as pumps, hoses, and cylinders.

This valve ensures that the hydraulic system operates within safe limits, thereby maintaining the integrity and longevity of the equipment. Without a properly functioning pressure relief valve, there is a risk of overpressurization, which can lead to catastrophic failures or leaks in the hydraulic system.
