Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A fluid regulating device comprising: a valve body defining an inlet, an outlet, and a valve port disposed between the inlet and the outlet; a port housing disposed in the valve body and defining a central cylindrical opening; a control element at least partly slidably disposed in the central cylindrical opening of the port housing and adapted for displacement along a central axis of the control element between a closed position engaging the valve port and an open posi…
