Patent ID: 6926249

Claim:
A globe valve providing a predetermined variable flow rate of fluid therethrough, the valve comprising: a valve housing having an inlet flow passageway and an outlet flow passageway; a valve port positioned within the valve housing between the inlet flow passageway and the outlet flow passageway, wherein the valve port defines a longitudinal flow axis between the inlet flow passageway and the outlet flow passageway; a valve plug movable along the longitudinal flow axis between an open position and a closed position to control the flow rate of fluid through the valve port, the valve plug having an outer surface extending along a longitudinal axis between a first end and a second end; at least one flow modulating channel recessed from the outer surface of the valve plug, wherein fluid flows through the valve port from the inlet flow passageway to the outlet flow passageway only through the flow modulating channel as the valve plug is moved between the closed position and the open position; a sealing member positioned along an inner surface of the valve port and sized to engage the outer surface of the valve plug, wherein the sealing member prevents the flow of liquid between the outer surface of the valve plug and the valve port; and a sealing ring mounted to the valve plug and positioned the first end of the valve plug, wherein the sealing ring engages the valve port to prevent the flow of fluid past the sealing ring when the valve plug is in the closed position.
