German process equipment supplier Coperion has unveiled its patented AutoAccess extraction system for rotary valves, a development aimed at simplifying maintenance in bulk solids handling installations.
The technology automates rotor extraction, enabling inspection, cleaning and maintenance procedures to be completed more quickly than conventional approaches. Coperion said the bayonet-lock mechanism allows operators to open the valve and extract the rotor in less than a minute without the use of tools.
The company believes the innovation will be particularly attractive to operators handling powders, granules and pellets in food, pharmaceutical and chemical sectors, where hygiene requirements and machine uptime are major priorities.
Alongside AutoAccess, Coperion introduced its new WFV diverter valve designed for hygienic gravimetric distribution of bulk materials. The company says the valve offers an economical approach to directing powders and granular products through processing plants. The developments form part of a broader push towards automation in bulk materials handling, where manufacturers are seeking to reduce maintenance labour, minimise downtime and improve process consistency.
