Prater rotary airlocks/valves can easily be configured to fit most application requirements. We manufacture specialized rotary airlocks with larger pockets, allowing up to 50% more volume, to enable them to run at lower speeds. Our innovative design means minimum air leakage, a longer life and a higher return on your investment.

After years of engineering and manufacturing rotary airlocks, we consider ourselves proven experts on the various rotary airlock designs available to our customers. Prater understands that temperature, pressure, size and construction plays a very significant role in processing various materials, which is why all of our rotary valves are carefully machined for those unique specifications.

Each of our rotary airlocks can be individually customized to your exact processing specifications to ensure a reliable, worry-free operation that meets your precise needs.
