As a Butterfly Valve Supplier, share with you. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly cuts off and throttles on the pipeline. The butterfly valve opening and closing part is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.

Butterfly Valve

Butterfly Valve is 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 the butterfly valve is required to control the flow rate, the most important thing is to correctly select the size and type of the butterfly valve so that it can work properly and effectively.

Generally, in throttling, regulating control and mud medium, the structure length is short and the opening and closing speed is fast (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, or strict sealing requirements, or severe abrasion, low temperature (cryogenic), etc., a special designed metal seal belt adjustment device is required for triple eccentric or double eccentricity 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 requirements, and operating temperature of -10 degrees to 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, 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.
