A pressure relief valve is a safety valve that is designed to automatically relieve the pressure in a system when it reaches a certain level. This helps prevent catastrophic failures and potential explosion of the system. Pressure relief valves are commonly used in industries such as oil and gas, chemical processing, and manufacturing, where high-pressure systems are common. They are also used in household applications such as water heaters and boilers. Pressure relief valves come in different types, such as spring-loaded, pilot-operated, and pneumatic, and the selection depends on the specific application and requirements.
