Fluoroplastic is commonly used as valve body lining,
cup ring and other seals. Because of its low price, and other
medium have little corrosion to the fluoroplastic except mild
alkali metals, high temperature chlorine trifluoride, fluorine
and other several medium, the
valve which made of fluoroplastic is to become omnipotence
corrosion-resistant control valve.
The limitation is its temperature resistant should only within
180¡æ, the pressure resistant could only reach 2.5Mpa,
also the its erosion resistant is poor, so it is required that
the pressure difference is the lower, the better, generally is
l.0MPa.
