At the same time, the outlet needs to be observed to check whether there is leakage. 　　　　

As long as we can do these things well, it will certainly make the sales of pneumatic ball valves very easy. After we master these basic sales skills, we can also accumulate more experience in the future sales process, so that we can make the whole sales better and better like a snowball.
