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 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 self-centering valve adapter connection assembly includes a first equipment flange that is connected to a second equipment flange with an adapter ring.
