Coperion ZVB rotary valve

Coperion has optimised its ZVB rotary valve design to provide gentle material handling, while maintaining the strict sanitary standards of the food industry. It has a lower overall weight, the same robust design, optimised housing wall thicknesses, increased inlet cross-section and an improved inlet geometry for fragile food materials such as roasted coffee and finished cereals.

This results in a gentler handling and introduction of product to the rotary valve. The increased anti-chopping inlet deflects the product into the rotating rotor chambers of the rotary valve and prevents the product being damaged by the metering vanes. It has an improved overall capacity.

The rotary valves are also available for wet cleaning (eg, clean in place). The overall design provides operational reliability for sanitary production. The materials are suitable for use with cleaning agents or hot water flushing, and the valve can be equipped with flush end sealing at the inlet and outlet, and between side covers and the housing.
