In the past, due to the low level of domestic valve design and manufacturing, many people had a large preference for butterfly valves, but developed countries such as Europe and the United States have been vigorously promoting and using butterfly valves. At present, butterfly valves are no longer the past. The development of butterfly valve has undergone the concentric development process of single eccentric butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve.

In my country, there are countless manufacturers engaged in valve production, because the valve industry is already quite mature and the market demand is very large. So, how can we choose a regular and reliable valve manufacturer? Below, the editor will tell you a few tips.

The pneumatic three-eccentric butterfly valve is another type of butterfly valve. It adopts a three-eccentric structure design and combines the pneumatic actuator to achieve fast, low friction operations. So what are the structure, working principle and advantages and characteristics of pneumatic three-eccentric butterfly valves?
