Another new product that Coperion has presented is the WFV bulk solid diverter valve, which can be used in various industries. This hygienic diverter valve offers an attractively priced solution for reliable gravimetric diverting of conveying material into gravity pipes. The WFV enables ideal product flow thanks to rounded shape of the rotating component. This bulk solid diverter is available in various versions. The gap-tight version is particularly suitable for no-pressure discharge in particular, but it is also suitable for applications with low or moderate system pressure. For this purpose, Coperion has developed a version equipped with various seals.

INSPECTION & MAINTENANCE
Coperion has presented new developments that optimise the conveying of bulk materials and component cleaning. The new, patented“ AutoAccess” automated extraction system for rotary valves simplifies inspection, cleaning and maintenance handling, considerably reducing downtimes. In addition, Coperion has introduced the newly developed WFV diverter valve, an economical and hygienic solution for gravimetric distribution of bulk materials.

Reducing cleaning times and increase machine availability
The automated AutoAccess extraction system significantly simplifies inspection, cleaning, and maintenance processes, increases machine availability, and lowers costs.
Automated rotor extraction increases process efficiency
With the automated AutoAccess rotary valve extraction system, Coperion has presented an innovative solution that significantly speeds up inspection, cleaning and maintenance processes. Where the valve previously had to be opened manually by removing the screws on the side cover and pulling out the rotor, handling is now markedly simplified by an automated process that is revolutionary for rotary valves. In under one minute, the new bayonet lock on the side cover of the rotary valve is mechanically unlatched using no tools and the rotor is then extracted linearly. The rotor and bayonet lock can then be moved to the side for better accessibility. This automation not only reduces effort and downtimes during inspections, cleaning, and maintenance, but also eliminates the need for a skilled technician to open and close the rotary valve. For cleanroom applications, fewer personnel need to be involved. Moreover, risk of damage to the rotor due to improper manual handling is reduced. Process standardisation and reproducibility are also possible for operators. Coperion has also redesigned the rotor coupling and bearing that are necessary for the rotor’ s extraction. Using the new coupling, the rotor can be moved into any angular position. The rotor no longer needs to be turned into a specific position in order to connect with the drive when inserting it into the housing. This quick, straightforward closing process further streamlines operations and increases machine availability. The external bearing arrangement of the rotary valve, with its proven shaft seal, prevents conveyed material from entering the bearing assembly, thus heading off potential damage to the rotary valve. This results in significantly longer service life and higher operational safety, especially when using abrasive or dusty products. In the course of the redesign, the bearing was modified and strengthened, leaving the rotor free to turn on the side cover in the extracted position and thus making it even easier to clean the rotor blades and chambers.
