What Occasions is the Butterfly Valve Suitable for?

As a 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 of the elastic valve seat material at high temperature. 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 a 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.

Butterfly Valve

Generally, in throttling, regulating control and mud media, the structure is required to be short in length and fast in opening and closing (1/4 revolution). Low pressure cut-off (small pressure difference), 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 under special conditions such as throttling adjustment, strict sealing, or severe wear, low temperature (cryogenic), etc., a special designed metal seal with adjustment device for triple or double eccentricity is required Butterfly valve.

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-sealed eccentric butterfly valve is suitable for the two-way opening and closing and adjustment of ventilation and dust removal pipelines. It 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, metallurgical, electric power and other fields. The gate valve and stop valve are good replacement product.
