A valve includes a valve stem that is rotatable through 90 DEG for opening and closing the valve. A lever sleeve is securely mounted to the exterior end of the valve stem, and includes at least one pair of diametrically opposite threaded apertures. An indicator cap includes a side wall that is mountable over the lever sleeve. The side wall includes an aperture. The indicator cap is mounted on the sleeve such that the aperture aligns with a selected one of the threaded apertures in the lever sleeve. A handle then is passed through the aperture in the indicator cap and is engaged in the threaded aperture of the lever sleeve for selectively rotating the valve stem. If an obstacle near the valve restricts rotation of the handle, the handle is removed, the indicator cap is rotated 180 DEG and the handle is positioned in the diametrically opposite threaded aperture of the lever sleeve.
