A flow selector device whose fluid flow is regulated by the rotational setting of a rotor body in a housing; and although the metering passageways have outlets spaced from the axis of the rotor and its manipulating shank, other passageways are provided in the housing, which channel the fluid then to an outlet in and concentric with the rotor and its flow-rate adjustment shank. One of those other passageways is an annular groove formed into the rotor\s manipulating shank, leading to a radial passageway in the shank, thus carrying fluid to the shank outlet channel regardless of the rotational setting of the rotor. Another of those other passageways is in the housing; and its provision is facilitated by forming it to open onto an outer face-portion of the housing, then sealing the outer portion of the passageways by a ball member forced into the outer end of the passageway. The rotor is held axially of the rotor by a snap ring, and by a nylon ring between the snap ring and the housing.
