Development history of PTFE lined valve technology

In recent years, with the development of technology, many chemical industries have utilized PTFE lined valve This is because a considerable number of industrial pipelines use a large amount of corrosive media, and ordinary valves are easily corroded in such pipelines, resulting in situations such as medium leakage, emission, dripping, and leakage. It should be noted that this situation poses certain hazards to both workers and enterprise assets. And PTFE lined valves can effectively solve such situations.
In the early development of PTFE lined valves, some companies used F3 and F4 as anti-corrosion materials for valve lining and achieved certain success. However, due to certain defects in F3, its application is not very widespread. Although F4 has strong corrosion resistance, it requires quite difficult processes to treat, resulting in high costs.
Many factories use lining materials for corrosion-resistant valves, including thermoplastic engineering plastics, silicate glass, ceramics, etc. With the development of the plastic industry, fluoroplastics, as an extremely corrosion-resistant new material, have widely entered the field of anti-corrosion.
At present, China's industrial technology is developing rapidly and has basically changed this passive situation. The PTFE lined valves developed not only have excellent quality and effectively solve various problems, but also have been exported overseas due to their high cost-effectiveness.
