The Difference Between Fluorine-line Butterfly Valve And Hard Seal Butterfly Valve
Mar 02, 2023
A fluorine-lined butterfly valve is one widely used valve in fluorine-lined valves.
Hard seals butterfly valve: with metal or hard materials in the sides, the sealing performance is poor but withstands high temperatures, resists abrasion, and machinery is inherently good.
Fluorine-lined butterfly valve: the butterfly disc and seat are wrapped with PTFE, which is a resistant corrosive media with, long service life, but can not withstand high temperatures.
The temperature of the hard seal butterfly valve is high, but the sealing performance is poor than the fluorine-lined butterfly valve, and the corrosion resistance is far inferior to the fluorine-lined butterfly valve.
