Product Introduction
When the double eccentric flange butterfly valve is opened, the disc quickly separates from the valve seat, significantly eliminating unnecessary excessive squeezing and scraping between the disc and the valve seat. This reduces the opening resistance distance, reduces wear, and increases the service life of the valve seat. Compared with the center line butterfly valve, the double eccentric flange butterfly valve has stronger high-pressure resistance, longer service life, and better stability.
