Widely used in food, medicine, chemical, petroleum，electric power, textile, paper and other industries and fields.
The eccentric principle is that the stem shaft is both deviated from the valve body center, also deviated from the seat.The double eccentricity effect allows the butterfly plate to quickly detach from the valve seat when the valve is openedGreatly eliminates unnecessary excessive squeezing and scraping between the butterly plate and the valve seat, reducesthe valve opening torgue, reduces valve seat wear, and improves the service life of the valve seat.
1.Streamlined disc design，reducing the flow resistance coefficient，making the fluid channel more stable，reducing pressureloss and reducing sensitivity for vavitation
2. Lining material can be selected according to different media
3. The automatic adjusting elastomer seat is fixed to the body
4. The selection of non-toxic, antibacterial, aging resistant, corrosion resistant rubber material, long service life
5. Bidirectional seal, zero leakage
