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.

Features & Benefits
- Reaction Bonded Silicon Carbide as a standard
- 30 times more wear resistant than stainless steel
- Each application is reviewed and the bore sized per the application for predictable in service performance
- Ideal for reducing flow and/or pressure in highly erosive services
- Transition between the ceramic liner and the housing may be specified as recessed or diamond ground to match sealing surface
- Manufactured from a single piece heavy wall thickness ceramic tube and not from ceramic tiles
