Applicable Occasions For Butterfly Valves

Butterfly valves are suitable for flow regulation. Due to the significant pressure loss of butterfly valves in pipelines, consideration should also be given to the robustness of the butterfly plate to withstand the pressure of the pipeline medium when closed. In addition, it is necessary to consider the limitations of the working temperature that the elastic valve seat material can withstand at high temperatures. The structural length and overall height of butterfly valves are small, with fast opening and closing speeds, and good fluid control characteristics. The structural principle of butterfly valves is most suitable for making large-diameter valves. When using butterfly valves for flow control, the most important thing is to choose the correct size and type of butterfly valve so that it can work properly and effectively.

Usually, in throttling, regulating control, and mud media, short structural length and fast opening and closing speed (1/4 turn) are required. Low pressure cutoff (small pressure difference), it is recommended to use butterfly valves.

Butterfly valves can be used for dual position adjustment, contraction channels, low noise, cavitation and gasification phenomena, small leakage into the atmosphere, and corrosive media.

When using butterfly valves under special operating conditions such as throttling adjustment, strict sealing requirements, severe wear, low temperature (deep cold), etc., special designed metal sealing belt adjustment devices with three or two eccentricities are required.

Butterfly valves are suitable for fresh water, sewage, seawater, saline water, steam, natural gas, food, medicine, oil, and various acid-base and other pipelines that require complete sealing, zero gas leakage during gas testing, high service life requirements, and operating temperatures between -10 ° C and 150 ° C.

Soft sealed eccentric butterfly valves are suitable for bi-directional opening and closing and adjustment of ventilation and dust removal pipelines, and are widely used in gas pipelines and waterways in metallurgical, light industry, power, petrochemical systems, etc.

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