Volkmann pneumatic vacuum conveyors are available with rotary valves that have a proprietary design that allows the conveyors to meter powders, pellets, granules, and other bulk materials in a continuous flow rather than transferring materials in pulsed plugs. Suitable for feeding mixers, extruders, reactors, and a variety of continuous processes without interruption, the rotary valves create a leak-proof seal that maintains the proper pressure differential between the vacuum receiver and hose or piping while consistently discharging the material for smooth, efficient, non-stop transfer.  

Typically specified as a companion with Volkmann pneumatic vacuum conveying systems, the rotary valves are manufactured from 100% stainless steel in product contact areas for sanitary processing and disassemble easily for quick cleaning. The rotary valves come in 4- and 6-in. diameters to accommodate a range of throughputs, capacities, materials, particle sizes, and other requirements and are ATEX certified as explosion-proof for use in hazardous and non-hazardous installations.
