Abstract: An in-line serviceable cutoff valve with excess flow capability includes a valve body and a separable cover. Internal valve components are accessible for service or replacement when the separable cover is removed from the valve body. The internal valve components may optionally be attached to the separable cover so that the separable cover and the internal valve components may be removed as a single assembly.

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: A fluid regulating device includes a valve having an inlet and an outlet and an actuator coupled to the valve and having a control assembly. The control assembly includes a control element and a diaphragm operably connected to the control element, the control element disposed within the valve and adapted to be displaced relative to a valve seat. A noise attenuation assembly is coupled to the outlet of the valve and includes a cylindrical body and at least one plate disposed in the cylindrical body, the at least one plate having an outer edge. An apparatus for retaining the noise attenuation assembly includes a plurality of rods coupled to the at least one plate. The plurality of rods includes at least one rod having a first end disposed through the outer edge of the at least one plate to support the noise attenuation assembly.

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.

Abstract: A valve including a control assembly that is configured to control fluid flow through the valve, The control assembly includes a driving element and a valve member. The driving element is rotatable about an axis between a first operating state in which the driving element maintains contact between the valve member and a valve seat and a second operating state in which the driving element does not maintain contact between the valve member and the valve seat. The valve member is rotatable about the axis independent of the driving element when the driving element is in the second operating state.

Abstract: An actuator assembly for use with a shut-off valve in a transport or storage system. The assembly is configured to be operatively coupled to a stem of the valve for controlling fluid flow therethrough. The assembly includes a mounting bracket coupled to the bonnet, a mounting sleeve coupled to the stem and movable relative to the mounting bracket, and an actuator having a body and an inlet formed in the body. The body is defined by a first body portion coupled to the mounting bracket and a second body portion coupled to the mounting sleeve and movable relative to the first body portion to expand or contract the body. The inlet is adapted to receive pressurized fluid; the body expands or contracts responsive to the pressurized fluid, and responsive to the expansion or contraction of the body, the mounting sleeve moves relative to the mounting bracket, thereby moving the stem.

Abstract: A self-centering valve adapter connection assembly includes a first equipment flange that is connected to a second equipment flange with an adapter ring. The adapter ring includes a first longitudinal flange with a tapered inner surface and a cylindrical outer surface. The adapter ring aids in centering the first and second equipment flanges while smoothing a fluid flow corridor between the first equipment flange and the second equipment flange.
