Abstract
The invention defines a position-indicating valve handle that is adapted to be mounted to the free end of a valve stem, wherein the handle includes a spiral groove in which a steel ball is free to move when the handle is turned by gravitational or magnetic force so that the ball will remain at a fixed point within the spiral groove (such as the lowest point where the handle is angularly disposed to the horizontal and gravitational force is used) as the handle is rotated. A transparent plate with indicia thereon is positioned to cover the spiral groove and allow the operator to visually determine by means of the location of the ball the approximate position of the valve stem within the body of the valve.
