Electric And Pneumatic Operated Straight Travel Fluorine-Lined Control Valve
Product introduction:
L2023011 straight-stroke lined control valve adopts the fluorine-lined structure of the valve body and internal parts, which effectively blocks the corrosion of all metal materials in the valve body by the corrosive medium. The inner cavity of the metal valve body is processed by teeth, so that the lining material is completely bonded to the metal, which increases the service life and performance of the lining material. The stem seal adopts the combination of RTFE bellows seal and V-PTFE packing to completely eliminate the leakage of the medium from the stem.Unbalanced ful-lined fluorine control valve is especially targeted at the use of highly corrosivemedia under low pressure and normal temperature conditions.

Product features:
1. Good corrosion resistance: The characteristics of the fluorine lining material inside the fluorine lined regulating valve enable it to resist the erosion of corrosive media such as strong acids and alkalis very well.
2. High precision flow regulation: The fluorine lined regulating valve adopts a secondary permeation structure, allowing the medium to be more evenly regulated, thereby achieving higher precision flow regulation.
3. Stability performance: The fluorine lined regulating valve adopts a reliable closed structure, which can avoid medium leakage and leakage, thereby greatly improving the stability performance of the valve.
4. Long service life: Due to the outstanding corrosion resistance, aging resistance and high temperature stability of the fluorine lining material, the fluorine lining control valve has a long service life.
