When a pressure increase is detected, the relief valve opens to vent the accumulated pressure, thereby allowing the system to return to a safe operating level. The operation of a relief valve is governed by the principles of physics; when pressure builds to a level that exceeds the spring force holding the valve closed, the valve opens. For spring-loaded relief valves, the system pressure pushes against the valve seat, lifting it open and allowing the excess pressure to escape.
