The present invention relates to valve plugs for reducing erosion of the valve plug head and/or seat. More specifically, this invention comprises a valve plug incorporating a choke transfer trim that reduces the time of exposure of the plug head and/or seat to high velocity and high pressure drop at the interface of the plug head and seat when the valve is in the closed position. The choke transfer trim transfers the flow control area of the valve away from the plug head/seat interface to a location downstream, thereby reducing erosion at the interface between the valve plug head and/or seat that is typically used for fluid throttling and shut off.
