The D971X electric wafer-type soft seal butterfly valve adopts a double eccentric structure, featuring a sealing function that tightens as it closes, ensuring reliable sealing performance. The sealing pair material is made of stainless steel, providing a long service life. The rubber sealing ring can be located either on the valve body or on the butterfly plate, making it suitable for media with different characteristics, offering users a choice. The butterfly plate uses a frame structure, which is high in strength, has a large flow area, and low flow resistance. The entire valve is painted with baked enamel, effectively preventing rust, and by simply replacing the sealing material of the valve seat, it can be used for different media. The D971X electric wafer butterfly valve has a bidirectional sealing function, and its installation is not restricted by the flow direction of the medium or spatial position, allowing installation in any direction. This valve has a unique structure, flexible operation, and is labor-saving and convenient.

Structural Features and Uses of Electric Wafer-Type Soft Seal Butterfly Valve

The D971X electric wafer-type butterfly valve adopts a wafer plate structure, mainly composed of the valve body, butterfly plate, valve shaft, valve seat, and transmission device. It is simple and compact in structure, small and lightweight, making it easy to transport, install, and disassemble. It opens and closes at 90°, with quick switching, low operating torque, and is labor-saving and lightweight. It has excellent sealing performance, a long service life, and can achieve zero leakage. Its flow characteristics are approximately linear, with good regulation performance. The D971X electric wafer butterfly valve uses rubber sealing, ensuring excellent sealing performance between the butterfly plate and valve seat when closed, with outstanding bidirectional sealing performance, low torque value, and the valve maintains its position under working pressure with minimal friction between the butterfly plate and valve seat. The valve is driven by the valve shaft to rotate the butterfly plate 90°. The butterfly plate opens and closes flexibly without sticking or jumping, with low torque. Uses: The soft seal centerline wafer-type butterfly valve developed by Shanghai Qigao Valve Manufacturing Co., Ltd., and the double eccentric flanged butterfly valve, are compact in structure, easy to switch at 90°, reliable in sealing, and have a long service life. They are widely used in water plants, power plants, steel plants, papermaking, chemical, light textile, food, and other industries for regulating flow and截流 media in water supply and drainage, and gas pipelines.
