Fluorine-lined Stop Valve Is Not Afraid Of Strong Corrosive Media

Fluorine-lined valves, also known as fluoroplastic-lined corrosion-resistant valves, are made by placing polytetrafluoroethylene resin on the inner wall of steel or iron valve pressure-bearing parts or the outer surface of valve internals by molding or inlaying, and using its performance in resisting strong corrosive media to make various valves and pressure vessels. The fluorine-lined stop valve is a branch of fluorine-lined valves. The opening and closing parts of the fluorine-lined stop valve are plug-shaped valve discs, the sealing surface is flat or conical, and the valve disc moves linearly along the center line of the fluid. The movement of the valve stem has two types: lifting rod type and lifting rotating rod type. Unlike other fluorine-lined valves, fluorine-lined stop valves are only suitable for full opening and full closing, and adjustment and throttling are not allowed.
Compared with other fluorine-lined valves, Lined Globe Valve has the following advantages:
1. Simple structure, convenient manufacturing and maintenance.
2. Small working stroke and short opening and closing time.
3. The valve has good sealing performance, small friction between sealing surfaces, and long service life.
In addition, the fluorine-lined stop valve is made of polytetrafluoroethylene, which is known as the "king of plastics", making it fearless of highly corrosive media. It can be used in various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, and strong oxidants at temperatures from minus 50 degrees Celsius to 150 degrees Celsius. It is also suitable for pipelines of various concentrations of strong alkali organic solvents and other corrosive gases and liquid media.
