D671F46 D671F46-10 D671F46-10C D671F46-10P Pneumatic lined butterfly valve

Overview of D671F46 D671F46-10 D671F46-10C D671F46-10P Pneumatic lined butterfly valve

D671F46 D671F46-10 D671F46-10C D671F46-10P Pneumatic lined butterfly valve is widely used in anti-corrosion pipeline system. It is mainly used to open, close and adjust the valve. Fully lined PTFE (F4), polytetrafluoroethylene (F3) and perfluoroethylene propylene (F46) fluoroplastic lined valves have the advantages of corrosion resistance, no leakage and long service life. It is applicable to concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing media or high-temperature alkene sulfuric acid, high-temperature concentrated acetic acid, acid-base alternation, various organic solvents and other strong corrosive media.

Features of D671F46 D671F46-10 D671F46-10C D671F46-10P Pneumatic lined butterfly valve

1. The center line butterfly valve is concentric (center line) between the entire butterfly plate and the valve seat within 360 ° circumference, with two-way sealing function, and the pressure and flow can be freely adjusted;

2. Four stage loading elastic seal absolutely ensures zero leakage inside and outside the valve;

a. The special transition curve at the circumferential joint of shaft head and butterfly plate and the reasonable interference of valve seat;

b. The end face of the shaft head is composed of an elastic O-ring, a rigid washer at the shaft shoulder and an elastic rubber pad;

c. The radial direction of the shaft adopts the combination of O-ring and metal pad;

d. The valve seat is embedded in the groove of the valve body with elastic strips;

3. Adjustable elastic marble is used for positioning. Accurate positioning and simple structure.
