The butterfly plate of the soft-sealing butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When it rotates to 90°, the valve is fully open. This type of valve should generally be installed horizontally in the pipeline. Soft sealing butterfly valve can be divided into flange type soft sealing butterfly valve and wafer type soft sealing butterfly valve according to the connection method.
1. Small and lightweight, easy to disassemble and maintain, and can be installed in any position;
2. The structure is simple and compact, and the 90° rotation can be opened quickly;
3. Small operating torque, labor-saving and lightweight;
4. The flow characteristics tend to be straight, and the adjustment performance is good;
5. The number of opening and closing tests is up to tens of thousands, and the service life is long;
6. The seals can be replaced, the sealing is reliable and can achieve bidirectional sealing, and the gas test leakage is zero;
7. The sealing material is resistant to aging and corrosion, and can be suitable for a variety of media.
