The primary function of a rotary valve is to regulate the flow of product from one chamber to another while maintaining a good airlock condition. This product is mainly in dry powder or granular form. In the dust filtration field, good airlocks are essential on cyclone and bag filter applications in order to maintain high dust collection efficiencies.

Airlocks are also important in the pneumatic conveying industry, where product is fed into a high pressure conveying line with minimum air leakage.
