Proprietary Design Meters Material Flow from Vacuum Receiver
Bristol, PA: Rotary valves from process equipment manufacturer Volkmann USA, Bristol, PA (https://www.volkmannusa.com), feature a proprietary design that permits the company's pneumatic vacuum conveyors to meter powders, pellets, granules, and other bulk materials in a continuous flow rather than transfer materials in pulsed plugs. Ideal 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 the company's pneumatic vacuum conveying systems, the Volkmann rotary valves are manufactured from 100 percent stainless steel in product contact areas for sanitary processing and disassembling easily for quick cleaning. The durable rotary valves are available in four- and six-inch diameters to accommodate a wide 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.
The Volkmann rotary valves may be tested on a full-size, fully operating pneumatic vacuum conveyor system in the company's Bristol, PA test facility. Testing may be viewed live on-site or streamed live online.
