How to choose the lining material for the clamp type fluorine lined butterfly valve

clamp-on Fluorine-lined Butterfly Valve It is a butterfly valve installed in the diameter direction of the pipeline, with a large rotation angle of 90 °. Plays an opening and closing role in the pipeline system to ensure reliable sealing of the pipeline. Clamp type fluorine lined butterfly valve It is characterized by small fluid resistance, temperature resistance, anti-aging, two-way sealing, reliable sealing, zero leakage, simple structure, small size, adjustable flow, etc. Due to the multi-layer soft stacked sealing ring of the clamp type fluorine lined butterfly valve being directly fixed on the valve plate, keeping the valve plate in a normally open state will affect the sealing performance when it is flushed by the positive medium. Due to structural limitations, clamp type fluorine lined butterfly valves cannot be made with a diameter of 200 or less. Due to the lining material of the butterfly valve being fluoroplastic, it is called a fluorine lined butterfly valve. There are many types of fluoroplastics, and different fluoroplastics are suitable for different media and temperatures.
1. Polyperfluoroethylene
Media: All organic solvents, inorganic acids, bases, etc; Temperature: -85 ℃ -150 ℃.
2. Polytrifluoroethylene
Media: All organic solvents, oxidizing acids; Temperature: -195 ℃ -120 ℃.
3. Polypropylene
Media: Inorganic salt solutions, inorganic acids, and bases; Temperature: -14 ℃ -80 ℃.
4. Polytetrafluoroethylene
Medium: strong acid, strong alkali, strong oxidant; Temperature: -200 ℃ -180 ℃.
