The Gatelock assembly is an economical, low-maintenance alternative to the traditional rotary airlock feeder that provides a positive seal that 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. The Gatelock assembly is available in sizes from 2 to 30 in. in diameter, and in any length desired.
