Characteristic & Application: Main construction characteristics of our 815, 830 series butterfly valve are wafer type and double flanged three eccentric type. Main construction characteristics of our 815L, 830L series butterfly valve is with protruding ears around body edge and designed as single flanged with screw holes. Our 815, 830 series butterfly valves are widely utilized in petroleum, chemical, industrial environmental protection water treatment, high building and water supplying & draining. The main advantages are: due to adopting three eccentric construction, sealing capacity is reliable, assuring disc never touch sealing seat when it starts, the problem of sealing seat burden unequally is solved, service life is prolonged, and assuring reliable sealing performance with advantages of high temperature resistant, wearable, anti-corrosion etc. Standards Design & Manufacture: API 609 Flange connection dimension: ANSI B16.5 Structure Length: ANSI B16.10 Test & Inspection: API 598 |
