Application of flange butterfly valve and wafer butterfly valve

Flange butterfly valve and wafer butterfly valve belong to the same category of butterfly valve. They have many similarities. In some working conditions, except for the size limit, they can be used in general. However, due to the different connection forms, their application fields are different in some working conditions.
 
In the water supply and drainage system, because the medium passing through the pipe is water, so the temperature and pressure are not large. In this case, it is OK to use flange butterfly valve or wafer butterfly valve. For the material, we usually recommend the customer to use ductile iron.
 
If the medium passing through the pipe is corrosive medium, no matter flange butterfly valve or wafer butterfly valve, fluoroplastics should be used as sealing surface material.
 
For the high temperature environment, both flange butterfly valve and wafer butterfly valve need to use metal hard seal.
 
When the pressure is too high, it is recommended to use the flange butterfly valve. The flange butterfly valve has its own flange, which is connected with the pipeline and has stronger compression resistance than the clip butterfly valve.
 
No matter the wafer butterfly valve or flange butterfly valve is used, it must match its working condition and structural parameters, otherwise it can not be used even if it is bought back, and will causing a huge hidden danger.
