The valve adopts three eccentric structure, seat and disc sealing surface are made of different hardness and stainless steel production, with good corrosion resistance, long life, with two-way sealing function of the valve, the valve vendors, products meet national GB / T13927 -92 valve pressure test standards. Valve Co., Ltd. Shandong Everbright wide production of this type of valve application, reliable quality, no leakage, leakage phenomenon, frequent switching is not stuck, rust, high temperature and high pressure valves, the majority of chemical plants, thermal power plants, steel mills , printing and dyeing, food plants the best choice. BD343H flange butterfly hard seal insulation jacket, also known as butterfly, is based on the common three eccentric metal seal butterfly valve on the external body welding a metal jacket, butterfly valve body on both sides of the insulation jacketed Interface , valve manufacturers can bypass the superheated steam or other gases, in order to prevent the media solidified or crystallized state at room temperature. Insulation valve flange than ordinary metal seal butterfly to freshman two specifications, mainly used in petroleum, chemical, metallurgical, pharmaceutical and other types of systems. The role of insulation valves is through the valve when the valve inside the insulation material to produce effective insulation medium at temperatures higher or lower case, the media will not condense or stick to the inside of the valve body, so that the proper functioning of the valve opening and closing, plant possible introduction of foreign advanced technology, based on the valve, 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 the carrier off fluid use.
