Development History Of Ptfe Lined Valve Technology

In recent years, with the development of science and technology, many chemical industries have used Lined Valve. This is because a large number of corrosive media are used in quite a few industrial pipelines. Ordinary valves are easily corroded in such pipelines, resulting in media running, bubbling, dripping, and leaking. It should be noted that this situation is harmful to both workers and corporate assets. The PTFE-lined valve can effectively solve this kind of situation.
In the early days of the development of PTFE-lined valves, some companies used F3 and F4 as anti-corrosion materials for valve linings and achieved certain success. However, due to certain defects in F3, its application is not very wide. Although F4 has strong corrosion resistance, it needs to be treated with a very difficult process, which makes the cost high.
The lining materials used for corrosion-resistant valves produced by many factories include thermoplastic engineering plastics, silicate glass, ceramics, etc. With the development of the plastics industry, fluoroplastics, as an extremely corrosion-resistant new material, have been widely used in the field of corrosion protection.
At present, the rapid development of industrial science and technology in my country has basically changed this passive situation. The PTFE-lined valves developed are not only of high quality and effectively solve many problems, but are even exported overseas because of their high cost performance.
