Abstract

A valve travel indicator is described. An indicator portion (34) indicates a location on a valve indicator scale (36). A retaining portion is fixedly coupled to the indicator portion (34) and movably coupled to a valve stem (26). The retaining portion fixedly couples the indicator portion (34) to the valve stem (26) during movement of the valve stem and movably couples the indicator portion (34) to the valve stem (26) in response to a predetermined force level exerted upon the indicator portion (34).
