What Material Is The Fluorine-lined Butterfly Valve Made Of?

The lining material of the fluorine-lined butterfly valve is fluoroplastic, and most of the materials on the market are polytetrafluoroethylene, codenamed PTFE. Polytetrafluoroethylene materials are highly resistant to corrosion and can be used in highly corrosive media such as strong acids and alkalis. At the same time, this material also has certain heat and cold resistance, and is suitable for temperatures between -196 and 200°C.

The temperature resistance range of polytetrafluoroethylene does not mean that the fluorine-lined butterfly valve can also be used. The valve is a consumable product. When the fluorine-lined butterfly valve is installed and used on the pipeline, it will be continuously corroded and washed by the medium. The temperature resistance range of the above-mentioned tetrafluoro material is obtained under ideal conditions. In reality, considering factors such as manufacturing process, production environment, and technical level, the temperature resistance of the fluorine-lined butterfly valve cannot meet the ideal requirements.

Advantages and characteristics of Lined Butterfly Valve

According to statistical observations and analysis, for the question of how much temperature the fluorine-lined butterfly valve can withstand, the manufacturers with good material performance can withstand up to 200°C, and the ones on the market generally reach 150°C.

1. Fluorine-lined butterfly valves rely on the excellent performance of polytetrafluoroethylene to effectively isolate the medium and the valve body, thereby achieving the purpose of corrosion prevention. They have been widely used in the fields of petroleum, chemical industry, environmental protection, etc.

2. Under normal temperature and pressure, fluorine-lined butterfly valves have a higher cost-effectiveness and can replace butterfly valves with stainless steel valve bodies.

Fluorine-lined butterfly valves are often used in working conditions with corrosive media, so when purchasing fluorine-lined butterfly valves, you must ensure the quality and safety of the valves and choose high-quality valve products produced by regular manufacturers!
