Coperion FX (full access) extraction devices for rotary valves have been developed especially for applications with strict hygienic requirements in food production. These systems offer free, unimpeded access to the rotary valve’s interior, for fast and easy cleaning or inspection. The newly developed FXL system is equipped with side-mounted linear guide bars that allow the rotor to be extracted from the housing with great ease and then later precisely re-installed without hindering access to the housing’s interior.
