Rotary Valve

The prime function of a rotary airlock valve is to regulate the flow from one chamber to another while maintaining a good airlock condition. The product is mainly in dry powder or granular form.

In the dust filtration field a good airlock is essential on cyclone and bag filter applications in order that the manufacturers quoted high dust collection efficiencies can be maintained. Airlocks are also important in the pneumatic conveying industry, where product is regulated into a pressure or vacuum conveying line while minimising air leakage.

Typical Applications

Gravity discharge of dust collectors, gravity discharge of cyclone dust collectors, provide airlock, control rate feeders for dilute phase and continuous dense phase pneumatic convey systems.

Handling products from feeding non-abrasive products by gravity to extremely abrasive products.

The handling products in dry powders and granular materials, such as sugar, cocoa, starch, flour, chemical ingredients, lime powder, china clay, fly ash and wood chips.
