Butterfly Valve Applicable Occasions

Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, the robustness of the butterfly plate to withstand the pressure of the pipeline medium should also be considered when it is closed. In addition, the operating temperature limitations of the elastomeric seat material at elevated temperatures must also be considered. The structural length and overall height of the butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making large-diameter valves. When the butterfly valve is required to be used for flow control, the most important thing is to correctly select the size and type of the butterfly valve so that it can work properly and effectively.
Usually, in throttling, regulating control and mud medium, the structure length is required to be short and the opening and closing speed is fast (1/4 turn). For low pressure cut-off (small pressure difference), butterfly valve is recommended.
Butterfly valves can be used for double-position adjustment, narrowing channel, low noise, cavitation and gasification, a small amount of leakage to the atmosphere, and abrasive media.
When throttling adjustment is required under special working conditions, or strict sealing is required, or butterfly valves are used under severe wear, low temperature (cryogenic) and other working conditions, it is necessary to use a specially designed metal seal belt adjustment device with triple eccentricity or double eccentricity. butterfly valve.
Butterfly valves are suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil and various types of valves that require complete sealing, zero leakage in gas test, high life expectancy, and working temperature between -10 degrees and 150 degrees. Acid-base and other pipelines.
The soft-seal eccentric butterfly valve is suitable for two-way opening and closing and adjustment of ventilation and dust removal pipelines, and is widely used in gas pipelines and waterways in metallurgy, light industry, electric power, petrochemical systems, etc.
Metal-to-metal wire sealed double eccentric butterfly valve is suitable for gas, oil, acid and alkali pipelines such as urban heating, gas supply, water supply, etc., as a regulating and throttling device.
The metal-to-metal surface-sealed triple eccentric butterfly valve is not only used as a program control valve for a large pressure swing adsorption (PSA) gas separation device, but also can be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields. It is an excellent choice for gate valves and globe valves. replacement product.
