Pneumatic valve fluorine-butterfly ball Q41F4 F46 / PFA - 16 c/P_ corrosion resistant anticorrosive pneumatic ball valve

Pneumatic valve fluorine-butterfly ball is dedicated to various containing corrosive medium in the pipeline corrosion resistant anticorrosive pneumatic valve, can be chosen according to different working conditions of different lining materials, such as F46, F4, PFA corrosion resistance, ageing resistance material. Such lining fluorine ball pneumatic valve has high chemical stability and corrosion resistance and reliable sealing, can be applied to any weak or strong corrosive chemical medium, such as various kinds of acid, alkali, salt and other corrosive medium and used as switch or adjustment.








pneumatic valve fluorine-butterfly ball with super corrosion resistance, pneumatic valve body cavity and body are package line 2. 5 - 3 mm thick F46, FA or PFA, acid, alkali, strong corrosion resistance, etc. , and small flow resistance, flow capacity is strong, good flow characteristic, USES the soft seal pneumatic seat, sealed performance is good. According to different control requirements, can choose assembly manual operation, the handwheel operation, electric control, or air control, different drive, can achieve the switch or regulating function!

pneumatic valve fluorine-butterfly ball instructions:



( 1) Use of medium temperature should not exceed 150 ℃ ( Medium in a short time to a temperature of 150 ℃, the use of long time temperature should be around 120 ℃) Pneumatic valve parts, otherwise, the lining F46 softening, deformation, the pneumatic valve closed tightly, big leakage.

（ 2) If users use the medium temperature, short time temperature under 180 ℃, temperature under 150 ℃ for a long time, can choose another kind of fluorine plastic a PFA, but lining PFA fluorine plastic price is more expensive, while supporting should be inquiry in advance.

（ 3) Don't have a negative pressure, the electric pneumatic valve fluorine-butterfly ball should avoid the use of pipeline in negative pressure, negative pressure, if any, of the pneumatic valve lumen lining of fluorine plastic layer sucked out ( Drum out) , shells, which leads to the pneumatic valves open and close down.

（ 4) Pressure and differential pressure should be controlled within the scope of the permit.
