The pneumatic wafer type titanium butterfly valve is a three-dimensional eccentric metal sealing structure, and the sealing type is metal-to-metal sealing. The special sealing system of this valve can ensure high sealing performance in all temperature ranges from ultra-low temperature to ultra-high temperature. The structural length and overall height of the pneumatic wafer type titanium butterfly valve are small, the opening and closing speed is fast, and it has good fluid control characteristics. When it is required to be used for flow control, it is most important to select the correct size and type so that it can work properly and efficiently. Pneumatic wafer type titanium butterfly valve is very corrosion-resistant in alkaline medium, and has very strong resistance to chloride ion (CI), and has excellent resistance to chloride ion corrosion. However, special consideration should be given to the fact that the pneumatic wafer type titanium butterfly valve has a tendency of point gaps and stress corrosion in the working medium, and natural explosion. Attention should be paid to catastrophic damage factors such as hydrogen embrittlement caused by hydrogen absorption of titanium due to various reasons. It is strictly forbidden to use titanium valves in the working environment where the above damage may occur.
