Valve trim and related methods are described. An example valve trim includes a cage defining a body having a bore to receive a valve plug. The cage includes a first passageway through a side surface of the body. The first passageway has an axis that is non-parallel relative to a longitudinal axis of the bore. A valve seat is to receive the cage. The valve seat has a first projection defining a first opening. The cage to be positioned relative to the valve seat in a first orientation to align the first opening and the first passageway to provide a first flow characteristic. The cage to be positioned relative to the valve seat in a second orientation to offset an alignment between the first projection and the first passageway to provide a second flow characteristic different than the first flow characteristic.

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.

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.

Valve trim and related methods are described. An example valve trim includes a cage defining a body having a bore to receive a valve plug. The cage includes a plurality of passageways through a side surface of the body that are radially spaced relative to a longitudinal axis of the bore. A valve seat to receive the cage. The valve seat has a plurality of projections defining a plurality of first openings and a plurality of second openings. Ones of the first openings to align with respective ones of the passageways to provide a first flow characteristic when the cage is positioned in a first orientation relative to the valve seat. Ones of the second openings to align with respective ones of the passageways of the cage to provide a second flow characteristic different than the first flow characteristic when the cage is positioned in a second orientation relative to the valve seat different from the first orientation.

An apparatus to identify proper loading for valve packing includes a packing follower for a fluid control valve. The packing follower has a cavity to receive a spring and at least a portion of a packing spacer. The apparatus also includes a first aperture disposed on an outer surface of the packing follower extending to the cavity to expose a portion of the spring.
