D943H electric hot butterfly

High temperature and high-pressure metal seal butterfly valve products are used in petroleum, chemical, metallurgy, electricity, food, medicine, water supply and drainage pipe on the road to a different medium, such as gas transport regulating traffic, cut off or turn on the best means of fluid. Choice of different materials, can be separately applied to oil, gas, water, sewage, water, air, steam, gas, flammable gas, corrosive media, oil, and food and other media, the maximum operating temperature up to 500 ℃, the maximum pressure can be up to 6.4MPa Features: Three eccentric metal seal structure, no mechanical wear, no leakage, excellent sealing function. Butterfly valve plate sealing surface is spherical (304 or 316 stainless steel) inner elastic ring seat circular surface (304 or 316 stainless steel) from contact with the seal, this is the best line-sealing effect, so that the sealing surface friction minimize shaft torque force also will be minimized. Applications territory: the current electric hot butterfly as a piping system used to implement off and flow control components, has been very widely used in many fields of petroleum, chemical, metallurgy, water, electricity. Connecting dimensions: Connection: Wafer, lug size: DN40 ~ 300 temperature: -40 ~ 160 Pressure: 16KG connection: ANSI, DIN valve plate: ductile iron, titanium, Hastelloy, stainless steel; lining EPDM Seat: EPDM , NBR, PTFE, FKM is suitable for small spoiler, drink, wear, corrosion, dry materials, pulp and other problems: First, because the multi-Flex stacked ring fixed in the valve plate, when the valve plate When the normally open state media form positive sealing surface erosion, and metal sandwich of soft seal by brushing with a direct impact on seal performance. Second, by the structural conditions limit the structure do not meet the following path DN200 valve, because the overall structure of the valve plate thick, large flow resistance. Third, because the principle of the three eccentric structure, sealing sealing surface between the valve plate and valve seat is to rely on the transmission of torque to seat the valve plate pressure. Positive flow state, the higher the pressure medium sealed tight squeeze. When the flow channel upstream medium with medium pressure valve plate and seat when positive pressure is less than medium pressure, the seal started to leak.
