Abstract
A technique enables control over flow in a wellbore with a flow control system. The flow control system combines a flow reduction mechanism with a flow control device, such as a valve. The flow reduction mechanism comprises a closure member which can be selectively moved between an unactuated and actuated position, allowing relatively greater flow through the flow control device in the unactuated position. The flow reduction mechanism actuates prior to or in conjunction with the flow control device to reduce flow and thus reduce the loading forces that would otherwise act against the flow control mechanism upon closure of the flow control device.
