Working principle of pneumatic butterfly valve:?
The pneumatic butterfly valve uses a round butterfly plate rotating with the valve head for opening and closing, so as to realize the starting action. The pneumatic valve is mainly used as a block valve, and can also be designed to have the function of regulating or section valve and regulating. At present, butterfly valves are increasingly used in low-pressure large and medium diameter pipelines.???

The pneumatic wafer type butterfly valve has a novel structure. The valve body structure is a short distance wafer type structure formed to meet the narrow pipeline space, with zero external leakage and internal leakage in line with national standards.
