Coperion and Coperion K-Tron WYK diverter valve for CIP cleaning

Monday, 08 April, 2019 | Supplied by: Brolton Group



Coperion and Coperion K-Tron has redesigned their stainless steel WYK diverter valve for CIP cleaning and the ZV rotary valve is now also available in larger sizes from 400 to 630.

Developed for powder and pellets, the diverter valve enables CIP applications to fulfil required criteria especially in the food sector; ie, 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.

During bulk material conveying, the conical rotor seals the conveying pipes to each other. During CIP cleaning, the rotor is minimally pulled out of the housing and flushed by the cleaning fluid. Now, the diverter valve has been optimised according to current EHEDG guidelines (Class I EL certification is currently in process). Coperion redesigned and optimised 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 realised 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. The diverter valve will be offered in Europe and Asia beginning of September 2019 and is expected to be offered in the USA by year end.
