Fluorine valve use and selection in valve fittings

Mar 21, 2018

The fluoridation valve used in the valve fittings has the function of switching and flow regulation in this valve fitting. On this point, it is also convenient to open and close the gas path, but it will not affect the flow and ensure the flow itself. Repeatability. The fluororesin valve in the valve fitting is specially used for controlling corrosive or highly corrosive medium, and the surface of the body cavity of the valve is covered with various fluoroplastics for selection.


The fluororesin valve in the valve fitting can be applied to different working temperatures and fluid lines when it is used, and in this case, the valve fitting will have higher strength and corrosion resistance. Better features.


Valves in the valve fittings are expensive in terms of price, but they are used in a very wide range of environments. They can be used not only in toxic and hazardous chemical environments, but also in various types of acids and bases with relatively strong corrosion performance. Or organic solvent, when it is improperly used, it will also have a relatively serious economic loss and very serious consequences. Proper use and maintenance of this valve fitting can extend the service life of the fluorine-lined valve, eliminate all kinds of accidents and ensure the normal operation of the pipeline.


The choice of material for the fluorine-lined valve in valve fittings is, first of all, PVC PVC. This type of material possesses relatively good (temperature 0-55°C) water resistance, concentrated alkali, and non-oxidizing acid. , Chain hydrocarbons, oils and ozone; for polypropylene RPP materials, can be used in (temperature -14 ~ 80 °C) inorganic salts of aqueous solutions, inorganic acids, alkalis, lean or concentrated solution.


Fluorine-filled valves in valve fittings are made of polytetrafluoroethylene PTFE (F4) material and can be used under conditions of (temperature -200-180) strong acid, strong alkali, strong oxidant, etc. The polyvinylidene fluoride PVDF (F2) material used can be used at a temperature of -70 to 100°C and is resistant to most chemicals and solvents.http://www.dmgcastings.com
