Our Rotary Valve Models

Model Range

Introduction:

The Grain Tech TFGF Series Rotary Valves are essential equipment units used in Pneumatic Conveying, Material Handling and Dust Removal Systems. They have been engineered to effectively maintain a pressure or vacuum state providing a continuous and smooth flow of material, or for controlling or preventing material particles from exiting to the atmosphere. The main component is the rotor, incorporated not only for metering and conveying materials, but also for sealing purposes.

These rotary valves are widely used in cereal, feed processing, oil and fat engineering, chemical, pharmaceutical, plastics production, mining, and other industries. The TFGF Series design is based on advanced Italian manufacturing, and its features are continuously being improved by our design team to fulfill the Industry requirements.

These rotary valves incorporate the following features:

• High reliability
• Compact size and heavy-duty structure
• Safe operation
• Light weight
• Large capacity
• Low power consumption
• Good appearance
