A pressure relief valve is designed to automatically open and release pressure when the system pressure reaches a certain setpoint, preventing damage to the system or equipment and ensuring the safety of the people operating it. The benefits of a pressure relief valve include increased safety and protection for the system or equipment, as well as peace of mind for the people operating it. Additionally, the use of a pressure relief valve can help to prevent costly repairs and downtime by protecting the system or equipment from damage caused by excess pressure.
