Selection of the following aspects should be considered a safety valve

Design of the choice of what type of safety valve, mainly determined by the characteristics of the process conditions and the working medium of the device. Under normal circumstances, boilers, pressure vessels, most use a spring-loaded safety valve. If the working medium container of toxic, flammable and explosive, the selection of a closed valve. Boiler and pressure vessel and safety discharge larger wall thickness and less affluent, and the best selection of low-pressure vessel safety valve.
Pressure relief valve is based on nominal range of design and manufacturing standard series, each Water Heater Gas Valves unit has a certain working pressure range. Boilers and pressure vessels shall be the selection of the appropriate choice of the maximum allowable working pressure safety valve.
Selection of safety valve emissions, its emissions must be greater than safety discharge device, so as to ensure the boiler or pressure vessel overpressure Aluminum safety gas valve can be discharged in the open part of the media, to avoid the pressure continues to rise inside.
