A dual-flow flapper valve assembly is presented having a flapper and a stopper that extends through an opening in a central portion of the flapper. In some embodiments of the present invention, a guide assembly extends downwardly from a bottom of the flapper and the stopper having a shaft that is received and extends through the flapper and the guide assembly, such that a top end of the shaft extends above the flapper and a bottom end extends below the guide assembly. In some arrangements of the present invention, the shaft has a plug adjacent the top end of the shaft and a stop at the bottom end.
