Does the shaft of Anshan electric UPVC butterfly valve need oiling? In our life and work, you will find that some things are very necessary, but some things are not so necessary. For pneumatic ball valves, there are some things you must know when using them, and some things you may not know are also OK. Is it really necessary to maintain the pneumatic ball valve? When you really have a better understanding of the overall issues, we can ensure that we can use it more reasonably in the future.
、 Material selection of pneumatic ball valve:
1. Metal composites; Material is a particularly important key factor, such as material characteristics, creep, thermal deformation rate, heat resistance, wear resistance, thermal abrasiveness and quenching temperature, which are the first things to be noticed.
