Abstract: A fluid regulator having a valve body defining an inlet, an outlet, a loading port, an access port, and a loading chamber disposed within the valve body and coupled to the loading port. A valve assembly is at least partially disposed between the inlet and the outlet and in communication with the loading chamber and is adapted to cooperate with the loading chamber to adjust fluid flow at the outlet by adjusting a fluid flow rate between the inlet and the outlet. A restrictor is at least partially disposed within the access port and the loading chamber and the valve assembly are adapted to be responsive to a change in loading pressure such that a modified rate is achieved and the restrictor is adapted to adjust a response speed in which the modified rate is achieved.

Abstract: A valve plug assembly (110) adapted for sealing engagement with a seat ring (126). The valve plug assembly includes a valve plug (140) having a sealing disk (150) adapted to engage a seating surface (154) the seat ring. The seating surface of the seat ring has a primary portion with a primary angle of any one of about 20 degrees to about 45 degrees and a secondary portion extending from the primary portion with a secondary angle of about 10 degrees. A retainer (160) is coupled to the valve plug and includes a body (166) having a first portion, a second portion, and a side extending from the first portion to the second portion at one of an angle of about 30 degrees to about 45 degrees. So configured, the stress acting on the sealing surface is reduced, increasing the service life of the sealing disk.

Abstract: An internal valve (100) includes a valve stem (106) disposed in a valve body (110), a poppet valve (102) coupled to the stem, and a bleed valve (104) is coupled to the stem. The valve stem is shiftable from a first position in which the poppet valve and the bleed valve are closed, to a second position in which the bleed valve is open, and a third position in which the bleed valve is closed and the poppet valve is open, and poppet may shift closed in response to a pressure change. The valve body includes a shoulder arranged (318) for sealing engagement with a container flange (304) and is between an inlet and a flange of the valve body and spaced away from the inlet, the shoulder arranged on the valve body to place the inlet a desired distance away from the inner wall of the fluid container (131).

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. The apparatus further comprises a second removable portion at a second end of the valve body to allow access to the first sealing disc from the second end, the second end opposite the first end.
