Multi-purpose rotary valve

round-flange

The use of plastic rotors in GEA Nu-Con demountable rotary valves has proved to be a sound solution for eliminating rotary valve scraping, which is a possibility with full stainless steel construction. However, plastic rotors are not suitable for all duties. For example, abrasive or high temperature products or for convey through applications which require stainless steel rotors to be used. For those applications that require abrasive or high temperatures (and with close tolerances), GEA Nu-Con has developed a special monitoring device to manage the potential risk of rotor scraping. Generation 3 RDS has been specifically designed also to meet the requirements of CIP (Clean In Place) with a setting allowance for dry out of the equipment, the re-designed RDS unit is more robust and has an ATEX compliance option. The complete Generation 3 assembly uses longer life bearings in the Rotary Valve unit, and a solid stainless steel rotor that means the rotor can be serviced. Retro fitting existing Generation1 and Generation 2 RDS and or Rotary Valves without RDS is also available. When fitted, this device continuously monitors the rotor and the valve housing, giving an immediate warning of any rotor contact, or even the presence of a metal shaving lodging between rotor and body.
