Ceramic Rotary Valves are rotary valves with rotor housing is lined with ceramic tiles and machined to very fine tolerances. It is characterized by high performance, high throughput and increases in service life by a factor of 10 to 20 compared with steel Valves depending on the material to be conveyed. Become the standard to replace old screw pump technology, which is very energy intensive and mostly unreliable with subsequent high maintenance costs.
