Pneumatic Fixed Ball Valve

In a general pneumatic fixation ball valve, its sphere and valve seat have an interference fit, and there will be an indirect interference during exercise. And with the pressure of some media, nonlinear behavior in the pipe will be likely to be destroyed to the sealing of the valve.

And the media transfer will squeeze the valve seat of the pneumatic fixed ball valve, and the valve seat will cause deformation, which is simple to generate displacement relative to the valve body, which is simple. This is also one of the basic reasons for the failure of pneumatic fixed ball valve seals.
