(6) We all know that if the ball valve is placed in the open air for a long time, it will easily rust the valve body and other parts, which will make it unable to use normally. It is not difficult to see that the ball valve should be stored in a waterproof, moisture-proof and anti-corrosion manner and tightly covered with a blue cover. If your ball valve has been stored for more than one year, it needs to be re leak tested when it is used again to ensure its stable performance. 　　　　

Now, when producing and manufacturing pneumatic high pressure ball valves, we often take measures to prevent secondary pollution. Even if there is pollution, we will adopt new technologies and methods to minimize the impact on the environment and people through technical improvement. For example, for a flange, in order not to hurt his hands during production, the head of the connecting bolt of the flange is generally designed as an arc, which is the embodiment of people-oriented.
