D971X Electric Butterfly Valve

Structural characteristics and applications of electric clamp type soft seal butterfly valves

The D971X electric clamp type butterfly valve adopts a clamp center plate structure, mainly composed of valve body, valve plate, valve shaft, valve seat and transmission device. The structure is simple and compact, compact and lightweight, and convenient for transportation, installation, and disassembly; 90 ° opening and closing, quick opening and closing, low operating torque, labor-saving and lightweight; Good sealing performance, long service life, and can achieve zero leakage; Its flow characteristics are similar to straight lines, and its regulation performance is good. The D971X electric clamp butterfly valve is rubber sealed. When closed, the butterfly plate and valve seat have good sealing performance, with excellent bi-directional sealing performance and low torque value. The valve maintains 100% zero leakage under working pressure, and the friction between the butterfly plate and valve seat seal is small. The valve is driven by the valve shaft to rotate the valve plate 90 degrees. The butterfly plate is flexible in opening and closing, without jamming or jumping, and has low torque. Usage: A soft sealed center line clamp butterfly valve developed by Shanghai Qigao Valve Manufacturing Co., Ltd. The double eccentric flange butterfly valve has a compact structure, easy 90 ° rotation switch, reliable sealing, and long service life. It is widely used in water plants, power plants, steel mills, papermaking, chemical, textile, food and other water supply and drainage systems, as well as gas pipelines, to regulate flow rates and intercept flow media.
