Rotary Valve – Global Flow Industries (GFI Valves)
Bulk Material Handling

GFI Rotary Valves

GFI Rotary Valves are designed for controlled feeding, metering and discharge of dry bulk materials while maintaining an effective airlock between different pressure zones. Their robust rotor construction and precision-machined clearances provide dependable performance in demanding material handling systems.

These valves are suitable for powders, granules, pellets, dust and other free-flowing bulk materials used in pneumatic conveying, dust collection, filtration and process handling applications.
