1. The center line butterfly valve is concentric (center line) between the whole butterfly plate and the valve seat within 360 ° circumference, with two-way sealing function, and the pressure and flow can be adjusted freely;
2. Four stage loading elastic seal absolutely ensures zero leakage inside and outside the valve;
a. The special transition curve at the circumferential connection of shaft head and butterfly plate and the reasonable interference of valve seat;
b. The end face of the shaft head adopts the combination of elastic O-ring, rigid washer at the shaft shoulder and 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 valve body groove with elastic strip;
3. The eccentric butterfly valve is two-dimensional. The cam effect caused by eccentricity will make the sealing pair produce enough sealing specific pressure. With the increase of working pressure, the sealing pair will produce enough sealing specific pressure, and the sealing effect is more ideal with the increase of working pressure
4. Flange connected double eccentric butterfly valve shall be used in occasions with high pressure. III. The design specifications shall comply with gb12238, API609, msssp-67 and msssp-68 standards
5. Adjustable marble positioning is adopted, with accurate positioning and simple structure (* O-ring is used to prevent accidental leakage)
