Acid Alkali Special Stainless Steel Flange Butterfly Valve

This acid and alkali stainless steel flange butterfly valve produced by our Shengshi Huagong Factory realizes the function of cutting off and regulating the medium in the pipeline by rotating the butterfly plate 90° around the valve stem axis. Its soft sealing structure is to coat the edge of the butterfly plate with elastic sealing materials such as rubber and polytetrafluoroethylene (PTFE), and use the flexibility of the material to achieve zero leakage or extremely low leakage; and the valve body, butterfly plate and valve stem made of stainless steel give the valve excellent corrosion resistance and can operate stably in a variety of corrosive media environments. With flexible installation methods such as wafer type or flange type, as well as diversified drive forms such as manual, electric, and pneumatic, stainless steel soft-sealed butterfly valves have become reliable fluid control equipment in modern industrial and civil pipeline systems.

The valve body of this acid and alkali stainless steel soft-sealed butterfly valve is made of high-quality stainless steel, and the common ones are 304, 316, 316L, etc. 304 stainless steel has good corrosion resistance and comprehensive performance, and is suitable for general corrosive environments, such as ordinary drinking water, air and other media transportation; 316 stainless steel adds molybdenum to 304, and its corrosion resistance is further improved, especially for chlorides, seawater, etc. It has better tolerance, and is suitable for chemical industry, marine engineering and other fields; 316L is an ultra-low carbon stainless steel, which reduces the carbon content and effectively avoids intergranular corrosion. It can still maintain good corrosion resistance after welding, and is often used in pharmaceutical, food and beverage industries that have extremely high requirements for corrosion resistance. These stainless steel materials have undergone strict smelting and processing technology to ensure that the strength, toughness and corrosion resistance of the valve body meet the use requirements.
