Ceramic and QTA Rotary Airlock Feeders

When encountering alumina, coke, fly ash, glass frit, and other highly abrasive products, the Ceramic Series rotary airlock feeder sustains its durability and achieves 3-5 times longer life compared to most other valves. A high-performance, thick wear layer of alumina ceramic coating maintains the valve’s precision tolerances longer. The Quick-Take-Apart Series (QTA) is made for applications where frequent removal of the valve internals is required. This valve permits tool-less removal of the rotor and end plate as one piece, eliminating the time-consuming step of “gapping” the rotor during re-assembly. There are no guide rails that require additional maintenance.
