Abstract
A valve position indicator for a valve includes an outer housing, actuation rod, indicator flag, and follower. The actuation rod is positioned within the outer housing, which is couplable to a tail stem protector of the valve. The actuation rod may have a helical slot formed therein. The actuation rod may be rotatably coupled to the outer housing. The indicator flag may be coupled to the actuator rod and may extend radially therefrom. The follower may be couplable 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 into the helical slot of the actuation rod when the valve position indicator is coupled to the tail stem protector.
