Introduction to Relief Valves
Relief valves are crucial safety devices used in a wide range of industries. Their primary function is to protect equipment, pipelines, and systems from over - pressure situations. When the pressure within a system exceeds a pre - set limit, the relief valve opens to release the excess pressure, preventing potential damage, explosions, or other hazardous events. They are commonly found in industries such as oil and gas, chemical, power generation, and water treatment. Relief valves come in various types, including spring - loaded relief valves, pilot - operated relief valves, and safety relief valves, each designed to meet different application requirements.
