In my opinion, people and objects should find their own suitable places, such as the pneumatic butterfly valve. If it is placed in the appropriate pipeline and used to control the flow direction of the entire pipeline medium, its role will be fully played, which will save the cost of selection and commissioning on the one hand, and facilitate the use on the other. If it is installed on the pipe to which the three-way pipe flows, or if the corrosive medium is restricted, it is easy to imagine the consequences. The pneumatic butterfly valve is equivalent to a pile of garbage.

3. The installation position of rubber seal ring is not fixed. It can be installed on either the butterfly plate or the valve body. It is very flexible and has its own characteristics, which can be selected by everyone.
