Rotary valves

Rotary valves or also called rotary airlock or rotary feeder is a mechanical device used in industrial applications to control the flow of materials—usually powders, granules, or pellets—from one chamber to another while maintaining an air or pressure seal between the two.

- It is light and compact dust valve
- For differential pressure up to 500 mbarg and easy to process products
- Body and covers made from high-tech GN40 nodular cast iron
- Outboard bearing, dust-tight and sealed for life
- Protective system up to 2,5 barg for products in dust class St1 and St2 (optional)
- ATEX 2014/34/EU certified (optional)

A rotary airlock is a mechanical device used in pneumatic conveying systems to control the flow of materials while preventing pressure loss.

It is designed with a rotary valve that creates an airtight seal between two areas, allowing material to move through while preventing air from escaping.

This design makes it possible for efficient movement of materials with minimal energy consumption.

Rotary airlocks are commonly used in dust collection, material handling, and temperature control applications.

They are also used in various solids handling processes to separate areas under different conditions (pressure) while allowing solid material to pass through.
