A fluid valve includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. A valve seat is disposed within the fluid passageway. A fluid control member is movably disposed within the fluid passageway, the fluid control member cooperating with a trim assembly to control fluid flow through the fluid passageway. The valve seat is clamped into the valve body and the fluid valve operates under choked flow at a pressure drop of 10% or less of the inlet fluid pressure.
