Rotary Air Valve

A rotary air valve, also known as an airlock or rotary valve, is a mechanical device used to regulate the flow of material between two or more chambers in a pneumatic conveying system. The valve consists of a housing and a rotor with vanes or blades that rotate inside the housing.

When material enters the valve, the rotor creates a seal between the inlet and outlet, preventing the backflow of air or gas from the downstream chamber. As the rotor rotates, it picks up a quantity of material and moves it to the outlet, where it is discharged into the downstream chamber.

Rotary air valves are commonly used in a variety of industries, including chemical processing, food processing, agriculture, pharmaceuticals, and cement manufacturing. They can be used to transport and meter a wide range of materials, including powders, granules, pellets, and other bulk solids.

Overall, rotary air valves are an essential component of many pneumatic conveying systems, ensuring a consistent flow of material and preventing air leakage, which can lead to process inefficiencies and product contamination.
