Pneumatic High Performance Double Eccentric Butterfly Valve
Pneumatic high performance double eccentric butterfly valve is further improved on the basis of single eccentric butterfly valve. Pneumatic high performance double eccentric butterfly valve structural feature is that the axis of the valve stem deviates from both the center of the disc and the center of the body. The double eccentric effect enables the butterfly plate to be quickly disengaged from the valve seat after the valve is opened, which greatly eliminates unnecessary excessive squeezing and scraping of the butterfly plate and the valve seat, reduces the opening resistance, reduces wear and improves Increased valve seat life. The pneumatic high performance double eccentric butterfly valve greatly reduced scraping also makes the double eccentric butterfly valve also adopt metal seat, which improves the application of butterfly valve in high temperature field.
