Pneumatic Double Eccentric Butterfly Valve
The pneumatic double eccentric butterfly valve is an improved version of the single eccentric butterfly valve. Its structural feature is that the axial center of the valve stem is offset from the center of the butterfly plate and the valve body. The double eccentricity effect allows the butterfly plate to quickly separate from the valve seat once the valve is opened. This minimizes unnecessary squeezing and scraping between the butterfly plate and the valve seat, reduces opening resistance and wear, and extends the valve seat's lifespan. At the same time, the pneumatic double eccentric butterfly valve can also use metal valve seats, which improves its performance in high-temperature applications.
