Abstract
A stop assembly for a valve is disclosed. Two stop rings are interfitted by meshing teeth and driven by a valve stem. In one embodiment, an escutcheon provides a mounting for one of the ring members as well as a stop surface for contact with both rings. The stop assembly provides a stop for maximum rotation of a valve member, as well as an adjustable temperature stop function.
