a cartridge housing defining a central longitudinal axis and a housing internal space; and
a valve assembly disposed within the housing internal space, the valve assembly comprising: (i) a valve stem comprising a valve stem head and a valve stem head support structure attached to the valve stem head and extending longitudinally to the cartridge housing and (ii) a valve sleeve,

wherein the valve sleeve has an oblong outer profile shape that extends around the valve stem head when the valve sleeve is in the closed position and that extends around the valve stem head support structure when the valve sleeve is in the open position, and
wherein the central longitudinal axis intersects the valve stem head and does not intersect the valve stem head support structure.
