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 sound treatment assembly includes an outlet member having a bore extending along a longitudinal axis, and a first flange portion is adapted to be coupled to portion of a valve body of a regulator valve. The first flange portion includes a contoured mating surface adapted to mate with a corresponding contoured portion of an exterior surface of the valve body. The outlet member also includes a second flange portion disposed at the second end. A diffuser assembly includes diffuser housing extending along the longitudinal axis, and a first flange portion is disposed at the first end of the diffuser housing and is adjacent to the second flange portion of the outlet member. One or more diffuser elements are disposed within an interior of the diffuser housing to reduce noise levels in the fluid exiting the outlet member.

Abstract: A fluid regulator includes an actuator, a body assembly, and a balancing system disposed between the actuator assembly and the body assembly. The actuator assembly includes an upper casing, a lower casing secured to the upper casing, and a diaphragm assembly disposed between the upper and lower casings. The body assembly includes a stem assembly operatively connected to the diaphragm assembly to move with the diaphragm assembly. The balancing system includes a diaphragm operatively connected to the stem assembly to move with the stem assembly. The lower casing of the actuator assembly includes a wall defining a portion of a balancing cavity that receives the balancing system and an inner surface that ends at a shoulder and has an annular groove formed therein that receives a portion of the diaphragm as the fluid regulator moves from a fully open position to a lockup position.

Abstract: Methods and apparatus to access and align sealing discs are disclosed herein. An example apparatus includes a cage of a fluid regulator, where the cage has a central aperture, and a valve stem to be received by the central aperture. The example apparatus also includes a diaphragm coupled to the valve stem, where an integral protrusion of the cage is to constrain a peripheral edge of the diaphragm against a removable portion of a valve body when the cage is coupled to the valve body.

Abstract: A balanced farm tap regulator includes a valve housing having a fluid inlet and a fluid outlet connected by a fluid passageway. A valve seat is disposed in the fluid passageway. A removable balanced plug assembly includes a valve stem having a stem balanced fluid passage, a disk that cooperates with a valve seat to control fluid flow, and a stem guide that is removably attached to the valve housing. The disk includes a disk balanced fluid passage that is fluidly connected with the stem balanced fluid passage. The stem guide is removably attached to the valve housing, the stem guide including an inwardly extending guide flange and an externally extending guide flange. The inwardly extending guide flange cooperates with the valve stem to form a balance chamber, and the stem balanced fluid passage is fluidly connected to the balance chamber and to the disk balanced fluid passage.

Abstract: Installing a fluid regulator in a fluid distribution system by: determining the position and orientation of the fluid regulator in the fluid distribution system; determining if a first opening and/or a second opening in the body of the regulator, are accessible with the fluid regulator in the determined position and orientation; installing the slam-shut device in the first opening, if accessible, and securing a plate over the second opening; and installing the fluid regulator in the fluid distribution system. The first and second openings are dimensioned such that the slam-shut device can be secured at least partially within the first opening in a first configuration and can be secured at least partially within the second opening in a second configuration.

Abstract: A valve plug adapted for sealing engagement with a seat ring. The valve plug includes a cylindrical body with an annular flange having a groove. A pair of bores is disposed in the body, each bore having a first diameter, a first end, and a second end disposed within the body. Each bore is also adapted to receive a fastener to couple the valve plug to a mounting portion, and a recess is disposed at the second end of the bore, forming a stepped portion. The recess is adapted to receive at least one of a portion of a retainer or a portion of the fastener. A sealing disk is disposed within the groove of the annular flange and is one of a machined sealing disk or a molded sealing disk.
