Abstract
A disc for indicating a position of a ball valve is provided herein. The disc includes a body having an outer circumferential edge and an inner circumferential edge. The inner circumferential edge defines an aperture configured to receive a valve stem. The disc further includes a first indicia and a second indicia circumferentially spaced about the outer edge of the body and circumferentially from one another. When connected to the ball valve, the first indicia is configured to indicate that the ball valve is in an open position and the second indicia is configured to indicate that the ball valve is in a closed position.
