Gate Lock

The Gatelock assembly is a 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. The Gatelock assembly is available in sizes from 2 to 30 in. in diameter and in any length desired.
