Abstract: A valve body having a ring of dissimilar material and a method of forming the valve body are described. The valve body includes an inlet, an outlet and a ring of dissimilar material. The method includes forming a valve core, splitting the valve core, placing a metal ring of dissimilar material between two pieces of the valve core, casting a valve body around the valve core, and fusing the metal ring to the valve body.

Abstract: A flow control device has a valve body having an inlet, an outlet, and a flow path connecting the inlet and the outlet and a unitary trim cartridge assembly secured to the valve body. The trim cartridge assembly has a cage disposed in the flow path, a bonnet coupled to the cage, and a retaining element disposed between the cage and the bonnet. The cage includes an exterior groove formed on an exterior surface of the cage, the bonnet includes an interior groove formed on an interior surface of the bonnet, and the retaining element extends into the interior groove and the exterior groove. A height of the interior groove and/or a height of the exterior groove is greater than a height of the retaining element to allow the cage to move longitudinally within the bonnet with the bonnet and cage assembled.

Abstract: A flow control device includes a valve body having an inlet, an outlet, and a flow path connecting the inlet and the outlet. A cage is disposed in the flow path, and a bonnet is coupled to the cage and includes a portion overlapping with a portion of the cage. A retaining ring is disposed between the cage and the bonnet. The retaining ring includes an interior side, an exterior side, and a cavity formed between the interior and exterior sides.

Abstract: Control valves including valve trim having relative movement between the bonnet and the cage. A control valve includes a valve body including an inlet, an outlet, and a flow passage connecting the inlet and the outlet. The control valve includes a cage disposed in the flow passage. The control valve includes a control element disposed in the flow passage and shiftable between a first position and a second position. The control valve includes a bonnet securable to the valve body and disposed adjacent the cage. The bonnet is adapted to receive a portion of the cage. The control valve includes a coupling formed between the bonnet and the cage that allows movement between the bonnet and the cage.

Abstract: A tool and a method are provided for cleaning a sealing surface of a valve body. The tool includes a stem adapted to be disposed in the valve body, at least one cleaning element coupled to the stem, and a handle operatively coupled to the at least one cleaning element via the stem. The at least one cleaning element includes at least one cleaning surface adapted to engage the sealing surface when the stem is disposed in the valve body. The at least one cleaning element is movable responsive to actuation of the handle such that the at least one cleaning surface cleans the sealing surface of the valve body.

Abstract: A high temperature ball valve seal is disclosed that achieves Class IV shutoff for operating temperatures above 550 degrees F. The ball valve seal includes a C-seal positioned between a main seal and a seal housing to prevent fluid from flowing through a secondary flowpath when the ball valve is in a closed position.
