2067143 9202750 PCTABS00010 A position indicating valve for controlling the flow of fluids includes a flow housing with a valve seat and a valve poppet. A control housing is provided adjoining the flow housing with a centrally located, nonrotating valve stem having inward and outward ends. The stem is connected to the valve poppet at its inward end and is threaded at its outward end with an intermediate portion being threaded oppositely. An operating handle is rotatably mounted to the control housing with a configured central aperture therethrough into which the threaded outward end of the stem extends. A configured position indicator and stop is threadably mounted on the outward end of the stem within the aperture and is adapted to actually move inwardly and outwardly of the handle as the handle is rotated. A rotatable coupling is located partially within the control housing and is interlockable with the handle and threadably mounted to and about the stem at the threaded intermediate portion. The coupling is adapted to axially move the stem, the valve poppet and the indicator in the same direction with rotation of the operating handle. The indicator has a greater magnitude of movement than the poppet.
