Diameter from 80mm – 2.300mm
For metering, sealing, feeding and discharging as well as measuring of bulk-solids in sticky, bridging and moist conditions, which tend to cause blocking, such as coal, salts, ashes, limestone, slurries and methyl cellulose.
Base of this design is our standard Rotary Valve. The forced cleaning ensures a correct discharge of every kind of material, which wouldn’t be possible with a standard model.
A scraper located below the rotor is driven by a synchronization gear. The scraper cleans each chamber, this process is maximzing the throughput and ensuring the proper function avoiding blockages of the adhering bulk product.
The sophisticated engineered geometry of our rotary-valves offers a minimum gap between the half-pipe shaped chamber and the scraper, thus enabling lowest possible residues.
Our product-range provides all the required options, designs and materials. It covers welded constructions in all standard material combinations with a variety of options and special equipment available to suit every special customer need in terms of properties of bulk solids and in-house-conditions. Depending on the application, we offer the self-cleaning rotary valves either heated or cooled as also process-optimized equipment such as leakage air collectors and overfill protections.
