There are three main components of a safety valve: disc, nozzle, and spring. The total capacity of the safety valve must be more than the maximum flow capacity (MFC) of the safety valve in case steam valves fail to open. Most steam boilers connect two safety valves in it, but it may require a third safety valve if it does not exceed the MFC.
