Titanium butterfly valve adopts the theme material titanium, which is a metal with high chemical activity. However, it shows particularly excellent corrosion resistance to many corrosive media. The reason is that titanium has a good affinity with oxygen, and it is very easy to react with oxygen to form a solid and dense passive oxide film on its surface. Titanium butterfly valves hardly corrode in the atmosphere, fresh water, sea water and high-temperature steam.

Titanium butterfly valve is suitable for flow regulation. Since the pressure loss of titanium butterfly valve in the pipeline is relatively large, which is about three times that of gate valve, when selecting titanium butterfly valve, the influence of pressure loss on the pipeline system should be fully considered, and the firmness of the butterfly plate under the pressure of pipeline medium when it is closed should also be considered. In addition, when selecting the elastic valve seat, the working temperature limit of the high-performance tetrafluorocarbon (graphite) composite plate sealing ring under high temperature must be considered.
