What are the types of pneumatic butterfly valves? Pneumatic butterfly valve is a kind of commonly used valve control instrument, which uses a round butterfly plate rotating with the valve stem for opening and closing, so as to realize the starting action. The pneumatic valve is mainly used as a block valve. There are many types of pneumatic butterfly valves. Today, I will introduce the classification of pneumatic butterfly valves. I hope it can help you.

Why some pipeline systems must use pneumatic butterfly valves
Pneumatic butterfly valves and rubber pipes are common pipe products of the management system, but some management systems must use pneumatic butterfly valves in design and construction. Why? Let's look at the answers:
Although the rubber pipe is soft and has strong fatigue resistance, it is relatively weak compared with the pneumatic butterfly valve in terms of pressure bearing, temperature resistance and aging resistance. In addition to the pressure and temperature in the pipeline system, there are also some influences such as fatigue, corrosion, vibration, squeezing, impact, etc. Therefore, under possible circumstances, it is most appropriate to use pneumatic butterfly valves to compensate for the displacement of the pipeline.
The pneumatic butterfly valve can be bent at will, and the internal stress caused by bending is very small. Therefore, it can bring great convenience to the pipeline design, and also plays an important role in the safe operation of the pipeline system. In the pipeline system design, if the pneumatic butterfly valve is connected in series with the tail pipe, it can not only receive the noise generated by the unit vibration, but also the noise caused by the fluid pulsation in the pipeline system.
