Features

Technical specification

4 models: 150², 200², 250², 300²

The drop through rotary airlock valves are designed to feed and discharge in a controlled way powders and bulk materials coming from silos, hoppers, pneumatic conveying installations, bag filters houses, cyclones. This rotary airlock valve is suitable when a high throughput is required. The effective flow rates are very variable depending on the materials flowing.
