What is the purpose of a pressure relief valve in hydraulic systems?

The purpose of a pressure relief valve in hydraulic systems is to automatically release excess pressure to prevent system failure. This component is critical for maintaining safety and functionality within the hydraulic system. Hydraulic systems operate under high pressure, and if this pressure exceeds the design limits, it can lead to equipment damage, hose failure, or even catastrophic system failure.

The pressure relief valve is designed to open at a predetermined pressure, diverting hydraulic fluid back to the reservoir or to a low-pressure area in the system. This not only protects components from damage but also ensures consistent operation by maintaining an optimal pressure range.

While other components may influence the flow rate or temperature within the hydraulic system, the primary function of the pressure relief valve is specifically to manage and alleviate excess pressure, thus safeguarding the system's integrity and operability.
