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.
Key Features
Accurate Material Feeding
Provides controlled and consistent discharge of dry bulk materials into downstream equipment.
Effective Airlock
Helps maintain pressure separation between conveying and discharge zones.
Precision Rotor
Precision-machined rotor construction supports smooth and reliable material transfer.
Wear Resistant Design
Robust construction is suitable for abrasive and demanding bulk material applications.
Continuous Operation
