S-AX dust valve
- Light and compact dust valve in GN40 nodular cast iron
- For differential pressure up to 500 mbarg and easy to process products
- Protective system up to 2,5 barg (St1 and St2)
Introduction
TBMA S-AX dust valves are specially designed to be used under dust filters and cyclones. Applications with a differential pressure up to 500 mbar where the valve primarily functions as an airlock or explosion barrier. The S-AX can be used as a protective system up to 2,5 barg for products in dust class St1 and St2. (optional)
These airlocks are made from GN40 nodular cast iron. This type of cast iron material is stronger and much less brittle than conventional cast iron, making it more resistant to shock loads, and has a high corrosion resistance. The installation weight of the S-AX is only 65 kg. The result is a particularly favourable price/quality ratio of this type of valves.
The S-AX valves are equipped with a round and a square connecting flange. This allows the valve to be used as a transition piece from round to square and vice versa.
