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 an autonomous protective system up to 2,5 bar for products in dust class St1 and St2. (optional)

These airlocks are made from GGG50 Smart-Lite™ 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 60,5 kg (standard version). 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.
