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.

Fluid regulators are disclosed. An example apparatus includes a vale body, a valve seat, and protrusions. The valve body has an inlet and an outlet. The valve seat is located within the valve body and is positioned between the inlet and the outlet. The protrusions are formed by and extend along an inner wall of the valve body between the valve seat and the outlet, and end adjacent the outlet. At least one of the protrusions is spaced relative to others of the protrusions. The protrusions are to increase a uniformity of a flow pattern of fluid flowing through a cross-section of the outlet. Each of the protrusions has a central axis oriented perpendicularly to a corresponding surrounding portion of the inner wall.

A supporting member supporting a valve body includes a supporting member body having a semispherical bottom portion that makes contact with the top face of the valve body and a securing recess that is provided in the center and at a predetermined axial location to adjoin a through hole provided in the valve body, and a securing member including an engaging portion that has a form of a shaft having a predetermined diameter made of an elastic material and protrudes from a proximal end and a securing projection that swells out from a predetermined axial location of the shaft portion to fit into a securing recess provided in a through hole in the supporting member body.

Fluid regulators are disclosed. An example a valve body including an inlet, an outlet, and an aperture disposed between the inlet and the outlet, the outlet includes surface structures to increase a uniformity of a flow pattern of fluid flowing through a cross-section of the outlet.

Pressure regulators with adjustable boost bodies are described herein. An example pressure includes a valve body defining a fluid passageway and an actuator casing coupled to the valve body, the actuator casing defining a pressure sense chamber and a channel between the pressure sense chamber and the fluid passageway in the valve body. The pressure regulator includes a plug assembly including a stem, a plug, and a stem guide. The stem guide has a flange with a notch. The plug assembly includes a boost body and a tube extending through the boost body. A first end of the tube is aligned with the notch and a second end of the tube is disposed in a downstream location relative to the seat such that the pressure sense chamber is in fluid communication with the downstream location. The boost body is rotatable with respect to the stem guide.

Pressure regulators with pivotable valve disk assemblies are disclosed. An example pressure regulator includes a valve body defining a fluid passageway between an inlet and an outlet, a seat positioned in the fluid passageway, a stem movable relative to the seat, and a disk assembly coupled to the stem, the disk assembly including a disk holder, an inner surface of the disk holder defining a cavity, a disk positioned in the cavity, the disk pivotable with respect to the disk holder to sealably engage the seat, and an alignment ring positioned between the inner surface and the disk, the alignment ring to provide a seal between the disk and the disk holder, the disk to compress the alignment ring when the disk pivots from a neutral position with respect to the disk holder, the alignment ring to bias the disk to the neutral position.
