Les vannes rotatives Kongskilde, type RF, conviennent à l'alimentation de granulés, (granulés, pellets, flocons, petits produits moulés, etc..) either into a pressurised pneumatic conveying line or as a metering feed to a subsequent process. The valves' design ensures minimal pressure losses when introducing products into a pressurised conveying line. The design of the RF version allows it to handle flake materiel such as might come from grinders.
