Titanium, the raw material of butterfly wafer titanium check valve, has a good affinity with oxygen, and is very easy to react with oxygen to form a solid and dense passive oxide film on its surface. In many harsh corrosive media, this oxide film is very stable and difficult to dissolve. Even if it is damaged, it can repair itself and regenerate quickly as long as there is sufficient oxygen. Butterfly wafer titanium check valve is based on the data of midline butterfly check valve provided by mark international control company. At present, this product is a new energy-saving product in China. It has good check performance, safety, reliability and small flow resistance. The butterfly wafer type titanium check valve produced by Shanghai silver shark is mainly applicable to chemical, food, pharmaceutical, textile, papermaking and energy systems as a one-way valve.
