Pneumatic fluorine lined butterfly valve

Butterfly valves are designed to adapt to corrosive environments with strong acids and alkalis, as well as the needs of various special fields such as petroleum, chemical, and food. PTFE is lined inside and on the valve plate of conventional butterfly valves to isolate the medium from the valve body and achieve anti-corrosion effects. Under normal conditions, it can replace stainless steel valve bodies and has a higher cost-effectiveness. The butterfly plate 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 at a rotation angle of 0 #176; ~90 #176; Rotate between 90 and; #176; At this time, the valve is fully open. In order to better adapt to the needs of modern automatic control.
