Main configuration characteristic of 815, 830 serives of butterfly valve is composed of wafer and faange three eccentricity, then main configuration characteristic of 815.830 series butterfly valve is edgeof body with protruding ears and single flange configuration with screw. 815, 830 series of butterfly valve has been widely utilized in petroleum, chemical industry and industrial environmental protection water treatment, haigh building, water supplying and draining. Themain characteristic is: Due to use three eccentric configuration, hermetic capability reliably, which ensure disc never touch sealingseat when it start, solve the problem of hermetical seat burden unequally, prolong service life, and ensure reliable hermetic capability with advantage of high temperrature resistant, wearable, antisepsis etc.
