What Occasions is Butterfly Valve Suitable for?

As a Flange Butterfly Valve Supplier, share with you. 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 when it is closed should also be considered. In addition, it is necessary to consider the limitation of the working temperature that the elastic valve seat material can withstand at high temperatures. 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 control flow, the most important thing is to correctly select the size and type of the butterfly valve so that it can work properly and effectively.

DIN3202 Flange Butterfly Valve

Generally, 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 revolution). For low pressure cut-off, butterfly valve is recommended.

Butterfly valve can be used when two-position adjustment, narrow passage, low noise, cavitation and vaporization phenomenon, a small amount of leakage into the atmosphere, and abrasive media.

When the butterfly valve is used in throttling adjustment under special working conditions, or requiring strict sealing, or severe abrasion, low temperature and other working conditions, it is necessary to use a three-eccentric or double-eccentric special butterfly valve with a specially designed metal seal with an adjustment device.

The butterfly valve is suitable for fresh water, sewage, sea water, salt water, steam, natural gas, food, medicine, oil and various products that require complete sealing, zero gas test leakage, high life expectancy, and working temperature between -10 degrees and 150 degrees. Acid-base and other pipelines.

The soft sealing eccentric butterfly valve is suitable for the 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, and petrochemical systems.

The metal-to-metal wire sealing double eccentric butterfly valve is suitable for urban heating, gas, water supply and other gas, oil, acid and alkali pipelines, as a regulating and throttling device.

In addition to being used as a large-scale pressure swing adsorption (PSA) gas separation device program control valve, the metal-to-metal seal triple-eccentric butterfly valve can also be widely used in petroleum, petrochemical, chemical, metallurgy, electric power and other fields. The gate valve and stop valve are good replacement product.
