Lined flanged butterfly valve Shanghai lined lined lined butterfly valve price, lined butterfly valves, flanges lined butterfly valves, flanged butterfly outline lined lined butterfly valves, lined butterfly valves, flanges lined butterfly valves, lined flanged butterfly The basic model: Lined butterfly (clip-on): D71FA-10 / 150Lb, D71F46-10 / 150Lb, D71F4-10 / 150Lb, D71F2-10 / 150Lb, D71PO-10 / 150Lb, D71J-10 / 150Lb; fluorine Butterfly (Flanged): D41FA-10 / 150Lb, D41F46-10 / 150Lb, D41F4-10 / 150Lb, D41F2-10 / 150Lb, D41PO-10 / 150Lb, D41J-10 / 150Lb; lined flanged butterfly valve, lining Flange Butterfly Key Features: lined flanged butterfly valve, flanged butterfly structure lining the middle sealed, stem and disc design as a whole, the disc rotated 90 °, the valve opening and closing process can be realized. For flange connection, clip-on. Midline sealing butterfly valve for the entire disc and seat in the 360 ??° circumference concentric with bi-directional sealing performance, pressure, flow can be adjusted freely. Butterfly small size, light weight, compact structure, compared with the same parameters gate, weight 35 to 60%. Butterfly corresponding lining material can withstand corrosion, using * seal structure, and with a special rubber elastic gasket sealing surface in place, good sealing performance. Shaft, disc circumferential groove joints using a special combination with a special O-ring sealed to prevent leakage of the medium, reaching zero leakage. Can configure multiple drives pneumatic, electric, hydraulic, etc., to achieve remote control box automation. Use and precautions lined butterfly: 1. Due to the multilayer soft stacked ring fixed in the valve plate, when the valve plate normally open state media to form a positive sealing surface erosion, erosion by post with a direct impact on sealing performance . 2, lined wafer butterfly valve, wafer butterfly valve lining restricted structural conditions of the structure do not meet the following diameter DN200 valves, because the overall structure of the valve plate thick, large flow resistance. Lined Wafer butterfly valve, wafer butterfly valve lining applicable at -50 ℃ ~ 150 ℃ of various concentrations of aqua regia, *, *, hydrofluoric acid and various organic acids, strong acids, strong oxidants, FEP is also applicable to a variety of The alkali concentration of the organic solvent, and other corrosive gases, the pipeline of the liquid medium used. Lined Wafer butterfly valve, lining Wafer butterfly with small size, light weight, lightweight operation, ease of installation, maintenance, simple structure, fast switching characteristics; applicable to various concentrations of less than 180 ℃ of aqua regia, *, *, hydrofluoric acid and various organic acids, strong acids, strong oxidants media. Widely used in petroleum, chemical, power, food, medicine, urban construction pipeline use. Shanghai decay Valve Group Co., Ltd.
