I. Product Introduction:
The D671X pneumatic soft-seal butterfly valve consists of a rubber-seal butterfly disc, a carbon steel or stainless steel valve body, and a valve stem. It is suitable for use in water supply and drainage, and gas pipelines with a temperature ≤120°C, such as in light textile, paper making, food, pharmaceutical, chemical, petroleum, electric power industries, etc., to regulate flow and cut off media. It features a simple structure, small volume, light weight, low material consumption, small installation size, quick opening and closing, 90° reciprocating rotation, and small driving torque. It is used to cut off, connect, and regulate media in pipelines, with good fluid control characteristics and shut-off sealing performance. It is widely used in water supply and drainage, sewage, food, heating, gas, ship, hydropower, metallurgy, energy systems, light textile, and other industries, and is especially suitable for occasions requiring bidirectional sealing and where the valve body is prone to rusting.

II. Product Features:
1. Novel and reasonable design, unique structure, light weight, and quick opening and closing.
2. Small operating torque, convenient operation, labor-saving and flexible.
3. Can be installed at any position, easy to maintain.
4. Replaceable sealing parts, reliable sealing performance achieving bidirectional zero-leakage sealing.
5. Sealing materials with aging resistance, corrosion resistance, and long service life.
