Fluoroplastic lined corrosion-resistant valves are made of polytetrafluoroethylene resin (or profile processed) by molding (or inlaying) on the inner wall of steel or iron valve pressure bearing parts (the same method is applicable to the lining of various pressure vessels and pipeline accessories) or the outer surface of valve internals, making use of its unique performance in resisting strong corrosive media to make various valves and pressure vessels.

Polytetrafluoroethylene, commonly known as "the king of plastics", was first developed by American supont C0., Ltd. in 1938. It was industrialized in 1949 and has a history of 50 years from the perspective of industrial application. However, it will not be long before it is widely used in the valve industry.

Among the corrosion-resistant materials, polytetrafluoroethylene has incomparable excellent performance. In addition to fusing alkali metals, elemental fluorine and aromatic hydrocarbons, it is also used in various concentrations of hydrochloric acid, sulfuric acid and nitric acid. Aqua regia, organic acids, strong oxidants, alternating concentrated and dilute acids, alternating bases and inert reactions in organic solvents. PTFE is lined on the inner wall of the valve, which not only overcomes the shortcomings of low strength of PTFE, but also solves the shortcomings of poor corrosion resistance and high cost of the main material of the valve. In addition, polytetrafluoroethylene has excellent chemical stability, good antifouling, anti stickiness, small and similar dynamic and static friction coefficient values, and good antifriction and lubrication performance. As a sealing pair of valve opening and closing parts, it can reduce the friction between sealing surfaces, reduce the operating torque of valves, and improve the service life of products. Its application range can also be extended to the food and pharmaceutical industries.

With the rapid development of modern industry. Fluoroplastic lining is a rapidly expanding application of corrosion method and its pipeline accessories in petroleum, printing and dyeing, chemical industry and other fields, showing strong vitality. As the preferred project in the project, it has attracted great attention and favor of various engineering design units and construction units. It is a sunrise product with great market potential.

Kangrui Valve Co., Ltd. has focused on this market for many years. On the basis of in-depth market research and unremitting efforts of scientific and technical personnel. We have successfully developed eight series of valves, including fluoroplastic Lined Butterfly valves, plug valves, ball valves, globe valves, diaphragm valves, check valves and gate valves, more than 1120 types of valves in four pressure levels, and various pressure vessels and pipeline accessories. Fluoroplastic lining materials have been expanded to PTEE (F4), rptfe (rf4), FEP (F46), PCTFE (F3) and PFA (soluble F4). In addition to more than a dozen kinds of PVDF (F2), polyolefin Po, PE, PP and PVC lining materials are added to meet the needs of various working conditions and parameters.

All employees of the company will make continuous efforts, explore and develop more and better corrosion-resistant valves under the guidance of the policy of "market-oriented, science and technology for development", so as to repay our customers who have consistently supported us for many years.
