Pneumatic double eccentric butterfly valve is high performance butterfly valve with high quality and long life. We can also provide fire-safe type butterfly valve with PTFE+SS316 seat.

The structural feature is that the stem axis is offset from the center of the disc and from the center of the body.

The double eccentric effect allows the disc to be quickly disengaged from the valve seat after the valve is opened, which greatly eliminates unnecessary over-squeezing and scraping of the disc and the valve seat, reduces the opening resistance, reduces wear and improves the seat life. 

The scraping is greatly reduced, and the double eccentric butterfly valve can also be used with a metal valve seat, which improves the application of the butterfly valve in the high temperature field.

With the help of advanced business philosophy and continuous technological innovation, we have developed rapidly in the Flange End Cast Iron Pneumatic Low Pressure Through Water Double Eccentric Ggg50 Butterfly Valve industry in recent years. The product design concept is advanced and the personality is outstanding. All products are based on the customer's interests and practical needs. After full demonstration and repeated comparison by expert designers, the final design is artistic and humanized. We have been chosen as the only supplier of long-term cooperation by many enterprises at home and abroad.
