Industry-specific characteristics of butterfly valves to high temperature, pressure range is higher butterfly valve nominal diameter large body using carbon steel, valve plate seal with a metal ring instead of the rubber ring. Large temperature valve welded steel plate manufacturing, mainly for smoke duct and gas pipelines hot medium. Shandong Everbright Valve Co., Ltd. wide production of this type of valve application, reliable quality BD343H flange insulation butterfly, no internal leakage, leakage phenomenon flanged butterfly, frequent switching is not stuck, rusted, the vast number of chemical plants, thermal power plants, steel mills, printing and dyeing, food plants the best choice. The role of holding the valve through the valve when the material holding the valve inside of the medium to produce effective insulation at temperatures high or low, so that the media will not condense or stick in the body inside, so that the valve opening and closing the normal operation of Weifang valve , plant introduction capable of foreign advanced technology, the use of sophisticated J-shaped elastic ring and three eccentric multi-level metal seal structure, is widely used in medium temperature ≤425 ℃ of metallurgy, electric power, petrochemical, and water supply and drainage and the municipal construction and other industrial pipe, for regulating the flow and load off fluid use.
