With the rapid development of industrial modernization in China, more and more automatic equipment is used in industrial activities, and valves are also widely used in these activities. Among them, pneumatic ball valve has become a widely used valve among many valves due to its unique characteristics, and it is very popular among users. What are the characteristics of pneumatic ball valves? What is its classification? Now, let's take a look.

The safety valve installed on the steam drum can be used as an extreme protection measure. Such measures should be taken when the production is abnormal and an accident is about to occur. The steam pressure regulating valve can not be protected with such extreme protection measures. It seems that the positive and negative action mode of the pneumatic control valve has a very important role. If it is not selected correctly, it will bring more trouble. I believe that you should understand this very well! For such a series of problems, we must understand them in detail.
