Safety valve selection principles

Safety valve selection principles
1, air or other gas stove safety valve, generally used in the entire Kai spring safety valve;
2, high-pressure bypass valve steam generating equipment, generally used in a safe and controlled dual function of the Pilot Safety Valves
3, if the medium temperature is higher, in order to reduce the temperature of the spring chamber, usually enclosed safety valve when the temperature exceeds 300 ℃ and open valve temperature than 350 ℃ and should be used in safety valve with radiator;
4, if the medium is corrosive and should be used bellows safety valve, preventing the important parts due to media corrosion and failure.
