The WYK bulk material diverter valve is suited for conveying powders with strict hygiene requirements such as lactose, infant foods, whey powder, or dry powder, and are Clean-In-Place (CIP) capable. It is typically used within pneumatic conveying systems for diverting bulk materials to various conveyors or for return transport of fines in spray drying processes.
For parts used in manufacturing processes the highest requirements in hygiene and purity apply. Moreover, frequent product changes and difficult product characteristics require regular wet cleaning. If cleaning expenditures can be minimized, companies can save significantly on time and costs.
The new WYK diverter valve enables CIP applications to fulfill required criteria especially in the food sector that come down to one thing: The diverter valve must be absolutely clean and free of contamination after wet cleaning — with no additional disassembly or manual cleaning. This saves time, effort and costs since manual post cleaning is not necessary. In doing so, the WYK diverter valve can easily be installed even at points that are poorly accessible.
Now, the diverter valve has been optimized according to current EHEDG guidelines (Class I EL certification is currently in process). Coperion redesigned and optimized the CIP-capable pipe sealing such that now operation with even the finest powders is possible. The pneumatic drives are separated — for turning and pulling the rotor, respectively — so that the rotor is supported on both sides. Along with its compact design, the diverter valve offers an improved cast design with increased surface quality. All materials conform to (EC) Regulation no.1935/2004 and the sealing materials are FDA-conform as well. Moreover, further flange connections, such as those per DIN 11864, can be realized simply on the housing.
The diverter valve is available in sizes DN 65, 80, 100 and 125. It is also available as a standard stainless steel diverter valve without the CIP cleaning function for non-wet cleaning applications.
