Cryogenic safety valves

Safety valves are special valves whose opening and closing parts are normally closed under the action of external forces. When the pressure in the equipment or pipeline exceeds a certain value, the medium is discharged to the outside of the system to prevent the pressure in the pipeline or equipment from exceeding the specified value. Safety valves belong to the automatic valve category and are mainly used in boilers, pressure vessels and pipelines to control the pressure not to exceed the specified value, playing a protective role in personal safety and equipment operation.
