A spring loaded relief valve is used in many applications to protect the over pressurization of vessels, pipes and containers. Conventional and balanced bellows relief valves are examples of spring loaded relief valves. Codes and standards like ASME, API,and ISO (to name a few) require that these relief valves are sized to have a relieving capacity that is sufficient to maintain the integrity of the system by preventing the internal pressure for exceeding the design limits. In general, the relief valve is designed and selected by the relief systems designer to meet process-engineering requirements.
