Abstract
A flow control device includes a valve body having an inlet, an outlet, and a flow path connecting the inlet and the outlet. A flow vane is coupled to the valve body and disposed in the flow path to divide a flow of fluid through the valve body. The flow vane has a first surface, a second surface, and a corrugation formed on at least one of the first and second surfaces. A control element is disposed in the flow path and movable in the valve body between an open position and a closed position.
