WA42F46 corrugated pipe pneumatic valve fluorine-butterfly security applications

corrugated pipe pneumatic valve fluorine-butterfly security ( WAF） Is a kind of corrugated pipe, lining for FEP ( F) Fep materials. Corrugated pipe lining fluoride security pneumatic valve installed in the pressure fluctuation of pressure vessel piping or equipment. Corrugated pipe pneumatic valve fluorine-butterfly safety is under external force open-close part in a normally closed state, when the equipment or piping within the medium pressure than specified value, through a discharge medium system to prevent the pipeline or equipment within the medium pressure in excess of the prescribed special pneumatic valves. Corrugated pipe pneumatic valve belong to automatic pneumatic valve fluorine-butterfly safety class, mainly used in boilers, pressure vessels and piping, control pressure shall not exceed the specified value, to protect personal safety and equipment operation plays an important role.
WAF pneumatic valve is widely used in corrugated pipe lining fluoride security containing sulfuric acid, hydrochloric acid, hydrofluoric acid, aqua regia and all kinds of organic acid, strong acid, strong oxidizer and other corrosive medium pressure vessel or pipe equipment.
pneumatic valve fluorine-butterfly security key features:
and corrosion performance: pneumatic valve body cavity, pneumatic valve, pneumatic valve, pneumatic valve stem from the whole line. PFA, F ~ mm thick, liquid ammonia, hydrochloric acid and other corrosive medium.
, prevent leakage performance: the pneumatic valve outside leakage prevention performance adopted corrosion PFA, F bellows, and the double seal of fluorine rubber o-rings, and equipped with (back pressure sealing device, ensure no leakage.
, sealed performance is: the adoption of the pneumatic valve core seat four fluorine lining ( PFA、F） Soft sealing structure, so the leakage level IV leakage of lower than the national standard GB/T standard.
pneumatic valve fluorine-butterfly security areas of application:
used in chlor-alkali, liquid chlorine, hydrochloric acid and other corrosive in chemical industry, harmfulness, pure, and contains a small amount of the adjusting control of solid medium.
this pneumatic valve fluorine-butterfly safety especially suitable for:
, as a rare expensive metal ( Hartz, tantalum, titanium, nickel, monel alloy) Pneumatic valve replacement.
and corrosive medium for poisonous and harmful to the environment.
, is used to react with metal medium, such as hydrochloric acid, liquid chlorine and other high-risk medium.
, used in biological engineering, and clean and pure medium surface adhesion of occasions. And used in the high permeability medium.
