Depends on the design - some just use a soft plastic tube that collapses in on itself to seal. That is why some inflating kits have long needle adaptors amongst others in them tapered or parallel.

The maximum pressure a check valve could withstand IMHO is probably far greater than the material used for that ball itself. So, if you over pressurise it then it bursts, usually from the weakest point, and from what i have seen near the seam but not the valve failing first.
