When the electric ball valve is in the open state, please note that this is a complete open state, and the thickness of the butterfly plate becomes the only resistance when the medium fluid works in the valve body. In this way, the pressure generated by the valve is much smaller. It is not difficult to see that the electric ball valve has a good flow control feature. In addition, there are two main types of seal, namely, elastic seal and metal seal. The former can be embedded into the valve body or directly installed around the butterfly plate, while the latter has a longer service life than the former, and cannot achieve integrity sealing. As for which one is needed, it depends on the actual situation. 　　　　

The simple structure of the pneumatic switch ball valve can make our maintenance easier. Any equipment needs timely maintenance in the process of use. If it is a relatively complex machine, you will find that the overall maintenance is very troublesome, and we may not be able to really repair it after doing a lot of work. Many people have encountered this situation. However, because of its simple structure, this valve is convenient and fast in maintenance. Anyone who has some knowledge of it can complete maintenance.
