6) Change the flow direction and improve the service life. The open type flows in the open direction. Cavitation and erosion mainly act on the sealing surface, so that the root of the valve core and the sealing surface of the valve core and valve seat are quickly damaged; The flow closed type flows towards the closed direction. Cavitation and erosion act below the sealing surface of the valve seat after throttling, protecting the sealing surface and the root of the valve core, and extending the service life. When the problem of prolonging the service life of the valve used as a flow to open type is more prominent, the service life can be prolonged by 1~2 times by simply changing the flow direction.

First of all, when there is a problem with the high pressure of the pneumatic ball valve, we must immediately shut down the use of the pneumatic ball valve itself, and then immediately find professional personnel to check what is going on. Never make trouble yourself, so that it is easy to have more serious problems. In addition, when the professional personnel are carrying out maintenance, we must pay attention to the explanation of the professional personnel, so as to avoid similar problems next time.
