Advantages and disadvantages of fluorine lined check valves in the chemical industry

Advantages: check valve A significant advantage in the chemical industry is its excellent corrosion resistance. Compared to other valves, many fluorine lined check valves are equipped with corrosion-resistant perfluoroalkoxy, which results in good performance. In the chemical industry, they can cut off strong corrosive media such as acids, bases, and salts, and also play a good role in some water treatment control systems. Furthermore, compared to ordinary check valves made of corrosion-resistant metal materials, fluorine lined check valves have certain price advantages.

Disadvantage: Compared to other valves, fluorine lined check valves actually only have one advantage of corrosion resistance. But its disadvantages mainly lie in sealing and temperature resistance. Especially in low-temperature environments, the casing of fluorine lined check valves may have condensation due to the low temperature of the medium, leading to rusting of the carbon steel casing; According to experiments, domestically produced fluorine lined check valves are more prone to internal leakage, with a higher probability than ordinary valves of the same type.
