Titanium, the subject material used in titanium butterfly valves, is a highly chemically active metal. However, it exhibits particularly excellent corrosion resistance to many corrosive media. The reason is that titanium and oxygen have a good affinity, and it is easy to react with oxygen to form a solid and dense passive oxide film on its surface. Titanium butterfly valve hardly corrodes in atmosphere, fresh water, sea water and high temperature water vapor. Titanium butterfly valves are suitable for flow regulation. Since the pressure loss of the titanium butterfly valve in the pipeline is relatively large, which is about three times that of the gate valve, when selecting the titanium butterfly valve, the influence of the pressure loss of the pipeline system should be fully considered, and the pressure of the pipeline medium should also be considered when the butterfly plate is closed. sturdiness. In addition, when choosing an elastic valve seat, the limitation of the working temperature of the high-performance tetrafluoro (graphite) composite plate seal ring at high temperatures must also be considered. When selecting titanium valve materials, it is necessary to fully consider the working temperature of the corrosive medium in the working condition, the composition of the medium, the concentration of each component, and the water content.
