Doc. 41 Hygienic Engineering of Diverter Valves in Process Lines for Dry Particulate Materials
First Edition, August 2011 - Every process plant is equipped with valves, which fulfil numerous functions. These include line shut-off, opening, change-over and control of product flow, while also giving protection against both excessive or insufficient pressure and intermixing of incompatible media at intersection points in the process line. Diverter valves are applied either when dry particulate material (product) flow has to be diverted into several directions during processing, or when product flow from different lines converges into one line. This Guideline deals with the hygienic aspects of diverter valve design.
