    Abstract: A balanced port control assembly includes a control element with a valve plug coupled to a valve stem and a pressure sensing labyrinth defined at least partly by the valve plug. The pressure sensing labyrinth provides for fluid communication between a sealing surface of the valve plug and a balancing diaphragm carried internally of the control element. The pressure sensing labyrinth includes at least one pressure sensing passage extending from the sealing surface and into the valve plug along a central longitudinal axis of the control element. So configured, fluid pressure resident on the sealing surface of the valve plug is also resident on the balancing diaphragm such that equal and opposite forces are applied to the control element.

    Abstract: A fluid regulator includes a balance port regulator valve and an actuator coupled to the regulator valve. The regulator valve has an inlet, an outlet, a valve port disposed between the inlet and the outlet, and a valve disc movable along a longitudinal axis between a closed position in which the valve disc sealingly engages the valve port and an open position in which the valve disc is spaced apart from the valve port. The actuator is responsive to fluid pressure to move an actuator stem along the longitudinal axis. A connector assembly operably and removably connects the valve disc to the actuator stem.

    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 slam shut safety device includes a valve body, a valve disc, a reset pin, and a reset pin guide. The valve disc is disposed within the valve body and shiftable along a slam shut axis between an open position and a closed second position. The reset pin is operatively coupled to the valve disc and shiftable along the slam shut axis relative to the valve body between an untripped position placing the valve disc in the open position and a tripped position placing the valve disc in the closed position. The reset pin guide supports one end of the reset pin, thereby providing added structural integrity to the reset pin and valve disc.

    Abstract: A slam-shut safety device includes a valve body and defining a flow path, a valve disc mounted on a valve disc support is movable between an open first position spaced away from the valve seat and a closed second position seated against the valve seat. A reset pin is operatively coupled to the valve disc support and is shiftable between an untripped position placing the valve disc in the open position and a tripped position placing the valve disc in the closed position. An anti-rotation assembly is carried by cooperating portions of the valve disc and the valve disc support, with the anti-rotation assembly comprising at least one protrusion and at least one receiving area sized to receive the protrusion, the anti-rotation assembly arranged to stop rotation of the valve disc relative to the valve disc support.
