The Kongskilde Rotary Valves, type RF, are suitable for feeding of granulates, (granules, pellets, flakes, small moulded products etc.) either into a pressurized pneumatic conveying line or as a metering feed to a subsequent process. The valves’ design ensures minimal pressure losses when introducing products into a pressurized conveying line. The design of the RF version allows it to handle flake material such as might come from grinders.
