Abstract
A precision modulating globe valve for controlling the flow of a fluid from zero to a maximum flow rate. The valve plug of the globe valve includes at least one flow modulating channel recessed from the outer surface of the valve plug. The outer surface of the valve plug engages a sealing member positioned along the inner surface of the valve port. The sealing member provides a fluid-tight seal between the outer surface of the valve plug and the valve port. The flow modulating channel is recessed from the outer surface of the valve plug from a minimum flow end to a maximum flow end. The radially recessed area of the flow modulating channel increases from the minimum flow end to the maximum flow end, such that as the valve plug moves past the stationary sealing member, an increased flow rate is created through the valve port.
