Prater Rotary Airlock Valves were tested at the Fike® Remote Testing Facility according to guidance found in NFPA-69. Fike® concluded that Prater Rotary Valves were structurally sound, exhibited no visually observable plastic deformation in any test and successfully isolated the protection region from flame propagation.
Our rotary airlocks have an innovative larger pocket design that allows up to 50% more volume which enables the rotor to run at lower speeds than other manufacturers’ rotary valves and feeders. Pair this with our exclusive self-adjusting packing glands and you have a rotary airlock valve feeder that provides minimum air leakage, a longer life, less maintenance and a higher return on your investment.
Other standard features such as our precision casting, CNC machining, compact design and universal mounting flanges allow for a versatile material handling air lock product that can fit virtually every existing bolt hole pattern and replace any existing rotary valve.
If you have a need for a rotary feeder, please consider the added “air lock” benefit of a Prater Rotary Airlock Valve. We are confident that we can help improve your bulk material handling and conveying efficiency.
