Overview

The domestically produced large-diameter electric hard sealed butterfly valve in the polycrystalline silicon industry is wear-resistant. The German VATTEN metal sealed triple eccentric butterfly valve uses an eccentric structure to achieve almost no friction between the butterfly plate and the valve seat during valve opening and closing. The torque of the valve stem is directly transmitted to the sealing surface through the butterfly plate, thereby eliminating the common jumping phenomenon when opening ordinary valves. This means that the eccentric butterfly valve can enter the adjustable area almost from 0 degrees to 90 degrees. Its normal regulation ratio is more than twice that of a typical butterfly valve, and the highest regulation ratio can reach 100:1 or more. This creates favorable conditions for the use of eccentric butterfly valves as control valves.
