A combination valve assembly is provided for controlling fluid flow through a housing within which a ball element is operatively positioned and has a throttle valve element operatively mounted within its bore. The ball element has a latching slot to receive a latching spline carried on the inner end of an outer sleeve-like stem that extends through the side wall of the housing. The throttle valve is operated by a stem extending inwardly along the outer sleeve stem which operates the ball element. The throttle valve element may be set for any desired size of fluid control opening, and may have either a bubble or a sealed closing-off fit within the bore of the ball element.
