The butterfly plate of the soft seal butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the valve body of the butterfly valve, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0 ° and 90 °. When it is rotated to 90 °, the valve is fully opened. The characteristics of the new high-life stainless steel butterfly valve and the problems in the use of the butterfly valve , this type of valve should generally be installed horizontally in the pipeline.
【Product Usage】
The butterfly plate of the soft seal butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the valve body of the butterfly valve, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0 ° and 90 °. When it is rotated to 90 °, the valve is fully opened. The characteristics of the new high-life stainless steel butterfly valve and the problems in the use of the butterfly valve , this type of valve should generally be installed horizontally in the pipeline. The soft seal butterfly valve can be divided into flange type soft seal butterfly valve , wafer type soft seal butterfly valve , welding type soft seal butterfly valve according to the connection mode .
【Features】
1. Small and light, easy to disassemble and maintain, and can be installed at any position;
2. The structure is simple and compact, and the 90 ° rotation is quickly opened;
3. Small operation torque, light and labor saving;
4. The flow characteristics tend to be straight, and the adjustment performance is good;
5. As many as tens of thousands of opening and closing tests, long life;
6. The seal can be replaced, the seal is reliable to achieve two-way seal, 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.
