Abstract: A control valve which includes a uniquely configured seat ring outfitted with flow passages adapted to operatively interact with a valve plug in a manner providing prescribed pressure reduction characteristics in a fluid flowing through the flow passages. The seat ring of the control valve of the present invention is preferably fabricated through the use of a direct metal laser sintering (DMLS) process. The use of the DMLS process to facilitate the fabrication of the seat ring in the control valve allows for the creation of more intricate and complex flow passages therein. Such increased intricacy/complexity provides better flow range/rangeability within the control valve.
