A safety valve is a special type of valve in which the closing element remains in a closed position under external forces. When the pressure of the fluid inside a device or pipeline rises above a specified value, this valve releases fluid outside the system to prevent the pressure from exceeding that specified level. Safety valves belong to the category of automatic valves and are primarily used in boilers, pressure vessels, and pipelines to ensure that pressure does not exceed specified levels, thereby playing a crucial role in protecting both human safety and the proper operation of equipment. Note: The safety valve must undergo a pressure test before it can be used.
