What is the function of the pressure relief valve?

The function of the pressure relief valve is to protect the pump from excessive pressure. This is crucial because a pump operates within a specified pressure range, and exceeding this range can lead to equipment damage, failure, or even hazardous situations. When system pressure rises to a certain level, the pressure relief valve opens to divert some of the flow away from the pump, thereby alleviating the pressure build-up and ensuring the system remains within safe operating limits. This helps maintain the integrity of the pump and the entire system, ultimately enhancing safety and reliability in operations.

Understanding the role of the pressure relief valve is vital for those working with water-based systems where pressure management is essential for performance and safety.
