Coperion, Weingarten, Germany, will be featuring its ZFD-CIP blow-through valve on Stand D1006 at SOLIDS Antwerp which takes place 27-28 March. This is the latest in the CIP series which has recently been approved by the EHEDG (European Hygienic Engineering & Design Group) and awarded EL Class 1 certification.
The interior and exterior surfaces of the rotary valve are extremely smooth. All corners and edges were designed with a large radius to achieve the best possible cleaning results. Surfaces in contact with the product are polished with a surface roughness of <0.8µm to prevent even the slightest product residues and contamination by microbial growth. The valve is made of stainless steel type 1.4404/AISI 316L. During fully automatic wet cleaning the rotary valve remains closed, saving time and money. To ensure that all fluids are fully removed from the interior during drying, special seals are used on the ZFD-CIP which are flush with the front and prevent capillary action.
EHEDG has tested this end-to-end hygienic design during several practical trials. The ZFD-CIP was approved with the EL class I certificate that provides proof of fully automatic CIP capability. If required, the ZFD blow-through valve can be manufactured with replaceable sealing cartridges and the FXS extraction facility which enables quick and simple rotor extraction from the housing. www.coperion.com
