A pressurizable game ball and valve includes a hollow spherical game ball formed of a rubber material or the like defining a pair of shell halves bonded together to form a spherical ball. An aperture extends through the shell half surface and an annular flexible disk valve is secured to the interior portion of the shell half overlying the aperture. The disk valve responds to the pressure differential between the ball interior and the ball exterior to communicate pressurized air into the game ball for pressurization and to maintain a sealing contact over the aperture during normal use.
