What Occasions Are Butterfly Valves Not Suitable For?

Butterfly valves are not suitable for:
Application requiring precise flow control: Butterfly has relatively low adjustment accuracy and is not suitable for application requiring precise flow control.
High pressure differentials or high pressure environment: In high pressure differentials or high pressure environment, butterfly valves may not meet sealing requirements, may leak.
High temperature medium: Some butterfly valves sealing material will fail or deform at high temperature, affecting sealing performance. Therefore, in the application of high temperature media, it is necessary to select butterfly valves made of special materials or to consider other types of valves.
Applications requiring complete sealing: While butterfly valves may provide some sealing performance, butterfly valves may not meet the required sealing standards in applications requiring complete sealing, such as the transport of high-purity gases or toxic and hazardous media.
Media containing solid particles or fibres: The butterfly valve may rub against solid particles or fibres in the medium during opening and closing, causing abrasion or blockage of the sealing surface, affecting valve performance.
Frequent opening and closing applications: butterfly valve disc is easy to wear during frequent opening and closing, shortening service life. Therefore, it may be necessary to consider other types of valves in applications that require frequent opening and closing. In short, when selecting valve type, we should take into account the dielectric characteristics, working pressure, temperature range, flow regulation requirements, sealing performance and other factors to ensure that the most suitable valve type is selected.
