Abstract: A balanced pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. A valve seat is disposed within the fluid passageway. A self-aligning valve plug is at least partially disposed within the fluid passageway, the self-aligning valve plug interacting with the valve seat to selectively open or close the fluid passageway. A retainer is partially disposed within a bore of the self-aligning valve plug and operatively connects the self-aligning valve plug to a valve stem having a ball portion. More specifically, the retainer includes a recess adapted to receive the ball portion of the valve stem, such that the self-aligning valve plug automatically rotates around the ball portion of the valve stem to achieve alignment and sealing engagement between a valve disc of the self-aligning valve plug and the valve seat.

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.
