Rotary Airlock Valves

Rotary Airlock valve is compact equipment which can provide controlled & continuous discharge of Powdery or granular material under gravity. Rotary Valve consists of a Rotor with Pockets and controls the feed by regulating the Rotor speed and filling ratio of pockets. Rotary valves have a very wide range of application and they are used to control the flow of the bulk material and dose the material proportionately.Rotary Airlock Valve helps manufacturers to quote high dust collecting abilities and maintaining the same. Airlocks are proven to be quite effective in the pneumatic conveying industry as well. Here, the product gets regulated into a vacuum or pressure to convey line while minimizing the present air leakage.

The main work of these valves is to serve as a lock that prevents loss of air whereas it also performs a vital product that handles various other functions. In other and simple words, these rotary feeders are an essential component for the efficiency of a conveying system. It is vital to understand that not all rotary valves are inevitably rotary airlock valves but effectively all rotary airlocks are air valves.
