Fully lined fluorine butterfly valve has excellent anti-corrosion performance and can be applied to any concentration of acid, alkali, salt, oxidant, reducing agent, organic solvent, etc. It has the advantages of corrosion resistance, no leakage, and long service life. Suitable for concentrated sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, aqua regia, various organic acids, strong acids, oxidizing media or high-temperature sulfuric acid, high-temperature concentrated acetic acid, acid-base alternation, various organic solvents and other strongly corrosive media.

Fully lined fluorine butterfly valve: 1. The center line butterfly valve is a butterfly plate and valve seat that are concentric within a 360 ° circumference (center line), with bidirectional sealing function, and pressure and flow can be freely adjusted; 2. Adopting adjustable elastic pin positioning. Accurate positioning and simple structure.

3. Four level loading elastic seal ensures absolute zero leakage inside and outside the valve; a、 The special transition curve at the connection between the shaft head and the butterfly plate circumference and the reasonable interference fit of the valve seat; b、 The end face of the shaft head adopts a combination of elastic O-ring, rigid washer at the shaft shoulder, and elastic rubber pad; c、 The radial direction of the shaft adopts a combination of O-ring and metal pad; d、 The valve seat is embedded in the groove of the valve body with elastic strips;
