Ceresist ceramic-lined chokes are specified for use in extremely erosive slurries that contain a very high percentage of solids. The large radius entry of the chokes exhibit better consistency and flow recovery characteristics than sharp-edged orifice plates. Furthermore, our ceramic-lined chokes are more compact than venturi-style chokes. The silicon carbide ceramic choke insert is 30 times more wear-resistant than stainless steel, and offers years of maintenance-free service.
