S-AX dust valve

The S-AX is made from GGG50 Smart-Lite ™ nodular cast iron, which is stronger and much less brittle, making it more resistant to shock loads than conventional cast iron. Consequently, this valve has a very low installation weight of only 60,5 kg (standard version).

The S-AX is suitable for applications with a differential pressure up to 500 mbar and can be used as an autonomous protection system up to 2.5 bar for products in dust class S1 and S2. (optional)
