Low-Maintenace Gatelock

Posi-flate’s Gatelock assembly is a low-maintenance alternative to the traditional rotary airlock feeder. The air-operated seat inflates to provide a long-lasting, high-integrity positive seal that can accommodate either full vacuum or pressure up to 100 PSIG. The seat automatically compensates for wear when it inflates against the disc, extending valve life. The Gatelock assembly can easily handle high cycling of dry granular or fine powdered materials and is available in sizes from 2- to 30-in.-diam, and in any length desired.
