Drop-through rotary airlock valve - Extraction and feeding of bulk materials
4 models: rate from 2.2 to 19.5 liters/rev.
Cast iron or stainless steel manufacturing
Rotary airlock valves are designed for bulk material extraction and dosing operations.
Rotary airlock valves are used for the dosing, feeding or discharging of fine-grained and powdered materials or granulates contained in silos, hoppers, pneumatic conveying installations, filters or even cyclones.
- Compact and robust design
- Easy access to internal mechanical parts for a quick and simple cleaning
- ATEX version
- High feeding accuracy

Dosing rotary airlock
Cast iron or stainless steel body.
Rotary valve under hopper
The drop-through rotary airlock valve feeds and discharges your bulk materials and raw ingredients in a controlled way.
Drop through rotary valve on industrial production line
The primary function of a rotary valve is to regulate the flow of the bulk material between two vessels while maintaining a good airtightness.
Hopper fitted with a rotary valve
Storage and conveying for dissolution of sugar in a weighed cast iron tank.
The processed bulk materials, here beet sugar and cane sugar, are vacuumed into a continuous discharge cyclone via a rotary lock to the dissolution tank.
Easy access to the mechanical parts
Easy access to internal mechanical parts for easy cleaning.
Rotary airlock on pneumatic conveying
For extraction and dosing the bulk material at the outlet of the cyclone.
Pneumatic conveying feeding
The rotary valve is used for the continuous depacking of bulk solids and raw ingredients from silos, hoppers, pneumatic conveying systems, filters and cyclones.

Powder handling - Rotary valve
From 2.2 litres/rev. to 19.5 litres/rev.
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.
