1, the center line butterfly valve is the whole butterfly plate and the seat in 360° circumference concentric (center line), with two-way sealing function, pressure, flow can be freely adjusted;
2, four-stage loading elastic seal, maximize the valve inside and outside zero leakage;
A. The special transition curve at the joint of the shaft head and the butterfly plate and the reasonable interference of the seat;
B. The end face of the shaft head is composed of elastic O-ring, rigid washer and elastic rubber pad at the shaft shoulder;
c, the radial axis adopts the combination of O-ring and metal pad;
d, the valve seat is inserted in the groove of the body with an elastic strip;
3, using adjustable elastic pin positioning. Accurate positioning, simple structure.
D341F46 flanged butterfly valves are widely used in anticorrosive piping systems. It is mainly used to open, close and adjust the valve. Fully lined with polytetrafluoroethylene (F4), polytrifluorovinyl chloride (F3) and polyperfluorinated ethylene propylene (F46) fluoroplastic lined valves have the advantages of corrosion resistance, no leakage and long life. It is suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua aqua, various organic acids, strong acids, oxidizing media or high temperature oleic acid, high temperature concentrated acetic acid, acid-base alternations and a variety of organic solvents and other strong corrosive media.
