Relief valve is a type of safety valve that is designed to open and release excess pressure from a system, such as a pressure vessel or piping system, to prevent damage or failure. It is typically used in industries such as oil and gas, chemical, and manufacturing.
When the pressure within a system exceeds a predetermined set point, the relief valve automatically opens to allow the excess pressure to escape. This helps to protect the system and its components from potential damage caused by overpressure.
Relief valves are commonly used in various applications, including steam boilers, pressure vessels, pipelines, and hydraulic systems. They are designed to be reliable, accurate, and able to handle high-pressure conditions.
There are different types of relief valves, including spring-loaded, pilot-operated, and balanced bellows relief valves. Each type has its own specific design and application, but they all serve the same purpose of ensuring the safe operation of a system by preventing excessive pressure buildup.
