Abstract: A control assembly can be configured for use with a pressure regulator having a valve body defining a fluid flow path. The control assembly can include a control member, a stem, and a lever, and can be disposed within the pressure regulator to selectively control fluid flow. The control assembly can include a primary control member and a secondary control member, or a mechanical stop that can operate to restrict flow along the fluid flow path, including when the stem disconnects from the lever.
