In industrial processing, handling, and material transfer systems, controlling the flow of materials while maintaining system pressure is crucial. One of the key components that facilitate this process is the rotary airlock valve. A rotary airlock valve, also known as a rotary valve or rotary feeder, is a mechanical device that regulates the flow of bulk materials (such as powders, granules, and pellets) between two chambers with different pressures. The valve operates by maintaining an air-tight seal while allowing materials to pass through in a controlled manner. This ability to manage material flow while preserving the pressure differential is what makes rotary airlock valves indispensable in many industrial processes.
