The pneumatic regulating butterfly valve is composed of an imported pneumatic actuator and a triple eccentric sealing butterfly valve body. The pneumatic regulating butterfly valve has a simple and compact structure, convenient processing, and is easy to make into a large diameter. The pneumatic regulating butterfly valve has a self-cleaning effect, a small resistance coefficient, and a large flow capacity. Equipped with a valve positioner, the operation can be controlled by inputting a control signal (4-20mADC) and a 0.44-0.7MPa air source. The pneumatic regulating butterfly valve is suitable for regulating the flow of suspended particles and thick and turbid slurry fluids. Clean media can be selected with valve plates and soft seals (rubber rings, PTFE rings) to reduce leakage (up to zero leakage), and triple eccentric hard seal valve bodies can be used for high-temperature and high-pressure conditions. Pneumatic regulating butterfly valve is a better device for regulating flow and cutting off fluid in automatic control system. Therefore, pneumatic regulating butterfly valves are widely used in pipelines with corrosive media such as metallurgy, power, petroleum, chemical, air, gas, combustible gases, and water supply and drainage, where the medium temperature is ≤ 550 ºC.
