Safety valves are special valves whose opening and closing parts are normally closed under the action of external forces. When the medium pressure in the equipment or pipeline exceeds the specified value, the medium is discharged to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. Safety valves belong to automatic valves and are mainly used in boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value, which plays an important protective role in personal safety and equipment operation. Note: Safety valves must undergo pressure tests before use.
