    Abstract: Embodiments of the invention provide an actuator (100) for a valve assembly. The actuator can include a yoke (146) with at least one bore (196), a first rod assembly (136), and a first slide member (148) seated within the at least one bore and pivotally connected to the first rod assembly. The yoke can be configured to rotate about a yoke axis (198) to actuate the valve assembly. The first rod assembly can be configured to move in a first direction transverse to the at least one bore and the yoke axis. The first slide member can be configured to slide telescopically within the at least one bore as the first rod assembly moves in the first direction to transmit torque to the yoke for actuation of the valve assembly.

    Abstract: A trim assembly for a regulator can include a cage and a plug assembly. The cage can include a peripheral wall defining an opening and a plurality of cage apertures formed in the peripheral wall. The plug assembly can include a plug and a sealing element and can be configured to be moveably received within the opening so that the sealing element contacts an inner surface of the cage to vary a flow area through the plurality of cage apertures depending on the position of the plug.

    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.
