Abstract
A valve position indicator for a valve includes a spline barrel, indicator flag, and follower. The spline barrel may be generally tubular and may be positionable about a tail stem protector of the valve. The spline barrel may have a helical slot formed therein. The spline barrel may be rotatably coupled to the tail stem protector of a valve. The indicator flag may be coupled to the spline barrel and may extend radially therefrom. The follower may be coupleable to a tail stem of the valve. The follower may extend in a direction perpendicular to the extent of the tail stem. The follower may extend through a slot in the tail stem protector and the helical slot of the spline barrel when the spline barrel is positioned about the tail stem protector.
