During the use of the fully welded ball valve, if the seal failure occurs, it will affect people's production. So what are the reasons for the failure of the fully welded ball valve seal?

In the general all-welded ball valve, the ball and the seat have an interference fit, and there will be indirect interference during the movement. And with the pressure of some media, the non-linear behavior in the pipeline will likely damage the sealing of the valve.

And the medium transmission will squeeze the valve seat of the fully welded ball valve, which will deform the seat for a long time. This phenomenon is simply that the seat of the welded ball valve is displaced relative to the valve body, which is also One of the basic reasons leading to the failure of all-welded ball valve seals.

Therefore, these reasons will cause the sealing failure of the fully welded ball valve. When these conditions are encountered, it needs to be resolved in time to ensure its good performance.
