Industrial A1 320 21.6 GC-II Rotary Discharge Feeder Valve

Zeppelin Systems' A1 320/21.6 GC-II Rotary Discharge Feeder Valve 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 (rotary airlock), allowing material to pass while minimizing air leakage between pressure zones. The unit features a cast housing with a welded multi-vane rotor, delivering consistent material flow and reliable sealing in demanding industrial environments. It handles powders, pellets, and granular bulk solids and is commonly mounted under silos, hoppers, or cyclones in plastics, chemicals, and food processing, as well as general bulk material handling. Key specifications include: Model/Part Number A1 320/21.6 GC-II; Operating differential up to approximately 1.0 bar; temperature range standard −10°C to +60°C; construction with shaft seals and minimized rotor clearance for low leakage; flanged inlet/outlet compatible with DIN and ANSI standards; and intended use in pneumatic conveying and bulk material dosing systems.
