Abstract: A fluid control valve includes a housing defining inlet and outlet passages and an opening in communication with the passages, with the opening extending along a main axis. A replaceable trim cartridge is configured to be removably insertable into the opening along the main axis. The replaceable trim cartridge includes a cage defining a piston chamber, a cage inlet, a cage outlet, and an internal flow control configuration extending between the cage inlet and the cage outlet. The trim cartridge further includes a piston head movable within the piston chamber. A plug is coupled to the piston head and includes an external flow control configuration. The plug is moveable within the cage between a closed position and an open position, with at least a portion of the plug being in contact with the cage when the plug is in the closed position to restriction fluid flow through the cage.

Abstract: A valve body, for use in a valve housing having an inlet and outlet, includes a spherical outer surface. A flow opening extends diametrically from one side of the outer surface to an opposing side. A plurality of flow control passageways extend from the outer surface into the valve body. The valve body is moveable relative to the valve housing between a closed position, a restricted flow position, and a free flow position. In the closed position, the flow opening and all of the plurality of flow control passageways are out of alignment with the inlet and outlet. In the restricted flow position, at least one flow control passageway is moved into fluid communication with the inlet and outlet to facilitate fluid communication therebetween. In the free flow position, the flow opening is moved into fluid communication with the inlet and outlet to facilitate fluid communication therebetween.
