Rotary Airlock Valves are used for regulating smooth flow of products or materials from one chamber to another under good airlock conditions, i.e., these valves act as 'airlock' seals between the inlet and outlet ports and completely restrict any form of airflow as the material like sugar, flour, ore, cement, fly ash, gypsum, coffee, cereals, pharma products, etc., move downward between the two ports. Usually, Rotary Airlock Valves are fitted to provide tight lock conditions in material conveying and processing system related to such crystals, dry powders, granules and pellets. 

We take utmost care in designing our range of airlock valves as an airlock valve with faulty construction can lead to product quality degradation, equipment malfunctioning, etc., at times even leading to abrupt process shutdowns. We offer a large selection of these valves for use in pressure and vacuum applications. These valves also find large scale use in the field of dust filtration, especially in cyclone and bag filter applications for improving the dust collection rate.
