Aerodyne, a division of Abanaki Corp., has added the Vacu-Valve Armadillo to its line of material-handling equipment. The Vacu-Valve Armadillo is a closed construction airlock valve that provides positive seal under hoppers, cyclones and dust collectors.

This dust-discharge valve requires no controls, lubrication or power source. The Armadillo's duckbill valve design allows free-flowing continuous discharge, automatically adjusting to the desired vacuum. Aerodyne's Vacu-Valve Armadillo is offered in carbon or stainless steel construction.

Sleeves for this airlock valve are available in neoprene, viton, and white nitrile, making it suitable for general use, high-temperature or food grade applications. Like its sister product, Vacu-Valve Platypus, the Armadillo can be found in such industries as foundries, mining, cement, pharmaceutical, cereal, plastics, chemical and manufacturing.

The Armadillo airlock valve has a durable enclosure making it useful in controlling dust in windy outdoor applications or in applications where the valve is not positioned close to the collection container. The enclosure has an easily removable access door.
