ZEPPELIN,A1 320 21.6 GC-II,ROTARY DISCHARGE FEEDER VALVE

Description:

The Zeppelin A1 320/21.6 GC-II is a rotary discharge feeder valve designed for controlled discharge and dosing of bulk materials in pneumatic conveying systems. It functions as both a volumetric feeder and airlock, allowing material to pass while minimizing air leakage between pressure zones. The unit features a robust cast housing with a multi-chamber rotor, enabling consistent material flow and reliable sealing in industrial environments.

Applications:

The Zeppelin rotary feeder valve is used in pneumatic conveying systems handling powders, pellets, and granular materials. It is commonly installed under silos, hoppers, and cyclones in industries such as plastics, chemicals, food processing, and bulk material handling. The valve ensures controlled material feed into dilute or dense phase conveying systems while maintaining pressure separation.
