Posi-flate, with offices in the USA and UK, will be exhibiting a double dump valve assembly at the forthcoming Powder Show in Rosemont, IL. This is designed to provide a low-cost and low-maintenance alternative to the traditional rotary airlock feeder and provides a positive seal that can accommodate either full vacuum or pressure up to 100 PSIG. The air-operated seat inflates to provide a long-lasting high integrity seal and easily handles high cycling of dry granular or fine powdered materials. The seat automatically compensates for wear when it inflates against the disc, extending valve life considerably. The Posi-flate double dump valve assembly is available in sizes from 50mm to 750mm diameter and in any length desired. The company will also be exhibiting a full line of inflatable seated valves as well as actuators, gravity diverters and its Vibra-Gate duplex valve at the show. www.posiflate.com
