DN200 Electric CF8 Soft Seal Wafer Butterfly Valve

Butterfly valve structure principle
Butterfly valve (also known as flap valve) is a regulating valve with a circular valve disc or disc as the closing part. It is mainly composed of a valve body, a valve stem, a butterfly plate and a sealing ring. The valve body is cylindrical, with short axial length and built-in butterfly plate. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. 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.

The thickness of the electric wafer butterfly valve is thinner than that of the flange butterfly valve. There are no flanges at both ends of the valve body, only a few guide bolt holes. The valve is connected to the flange at the pipe end with a set of bolts/nuts, which is generally applicable Suitable for places with narrow space or restricted pipelines. The advantage is that it is easier to disassemble, the valve cost is lower, and it takes up less space. However, the disadvantage is that if there is a problem with one sealing surface, both sealing surfaces have to be disassembled!

There are flanges at both ends of the electric flange butterfly valve body, which are connected to the pipeline flange. The sealing performance is more reliable than that of the wafer butterfly valve. It is generally used in places with larger diameters or higher pressures, but the cost is relatively low. Clamp butterfly valve high.
