ABSTRACT:
As useful in a filter device for diverting fluid flow either through a filter medium or directly in by-pass thereof, there is disclosed a valve stem for a fluid diverter valve to divert water from an inlet in the valve selectively to each of two outlets in the valve, and a compressible o-ring surrounding the valve stem and forming a fluid tight seal between the outlets. The valve stem fits in a cylindrical bore of a valve body having an inlet and first outlet perpendicular to the axis of the stem, and a second outlet in axial alignment with the stem. Radial conduit means in the stem are aligned with the valve inlet and first outlet. One end of an axial conduit in the stem is aligned with the inlet of the valve and the other end of the axial conduit opens to the second outlet.
