A ball check valve includes a mounting base, a valve cage and a valve ball. The valve cage is mounted on the mounting base and includes a base, multiple holding fingers and a filtering and regulating device. The holding fingers are formed on the base and are arranged to form a valve chamber. The filtering and regulating device is mounted on the holding fingers, includes multiple curved ribs respectively mounted on a pair of corresponding holding fingers and are arranged in parallel with the base of the valve cage to filter impurities in and regulate fluid flow through the ball check valve. The valve ball is movably mounted in the valve chamber to selectively open and close the check valve. Consequently, the ball check valve can not only service as a check valve, but also service as a filter and regulator for the fluid flow.
