Handle PTFE Seat Butterfly Valve
The PTFE butterfly valve is to meet the needs of some special fields such as petroleum, chemical industry, food and so on in some corrosive environments with strong acid and strong alkali. The butterfly valve body made of PTFE has a strong anti-corrosion effect. Under normal conditions, it can replace the stainless steel valve body and has a higher cost performance. The butterfly disc of the butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is fully opened
