What is a safety valve?

  The safety valve is a special valve whose opening and closing parts are normally closed under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, the medium pressure in the pipe or equipment is prevented from exceeding the specified value by discharging the medium outside the system . Safety valves belong to the category of automatic valves, which are mainly used in boilers, pressure vessels and pipelines. The control pressure does not exceed the specified value, which plays an important role in protecting personal safety and equipment operation. Note Safety valves must be pressure tested before they can be used.
