Abstract
A skirt guided control valve provides streamlined flow and minimum resistance to flow in flow up and flow down conditions when the valve is open. The skirt guided control valve has a fluid inlet, a fluid outlet, a passageway disposed between the fluid inlet and fluid outlet, a valve seat and a valve plug with a skirt. The valve seat and the skirt portion of the valve plug include blended edges and contoured surfaces to provide for streamlined flow.
