Feeder/Airlock Valves

The BT Series Blow-Through Feeder/Airlock is designed to ensure optimal bulk density and throughput of hard-to-convey materials such as fine powders and flakes that, in high-pressure pneumatic conveying applications, can easily over-aerate and reduce material feed efficiency. The product’s design decreases excess aeration of the material during conveying with an integrated vent port on the return side of the valve housing that automatically vents air leakage. The BT Series 8-vane rotary valve design significantly reduces air leakage and maximizes the flow path of air through the rotor pocket; improving material pocket release. The minimal air leakage, and resulting low, effective pressure drop of the BT Series optimizes material flow density, improves material conveying efficiency, and reduces total compressed air consumption. ACS Valves BT Series Blow-Through Feeder/Airlock housings are available in cast iron, or, 304 or 316 stainless steel; in either 8-in. or 10-in., round flange sizes. The BT Series is available with a hard chrome housing interior, and with adjustable rotor tips.
