The Vacu-Valve Armadillo is a closed-construction airlock valve that provides positive seal under hoppers, cyclones, and dust collectors. Because this dust-discharge valve requires no controls, lubrication, or power source, it is both energy saving and maintenance-free — allowing it to operate for about one-sixth the cost of a rotary airlock valve used for discharged dust or abrasive materials. The Armadillo’s duckbill valve design allows free-flowing continuous discharge, automatically adjusting to the desired vacuum. The valve is offered in carbon or stainless steel construction. Sleeves are available in neoprene, viton, and white nitrile, making it suitable for general use, high-temperature or food grade applications.
