Flanged shut-off butterfly valve for drinking water: DVGW

The AK211W shut-off butterfly valve was designed specifically for drinking water applications. The Body is made of GGG40 (EN GJS 400-15) with an epoxy resin coating, the Disc is made of stainless steel 1.4408 (CF8M), and the sealing sleeve is made of EPDM. The shut-off butterfly valve is DVGW-certified for drinking water. Thanks to the standardized (EN ISO 5211) mounting flange, all valves from FERGO Armaturen GmbH can be automated very easily; we will also be pleased to do this for you. The AK211W is also available in the wafer version (WAFER) and has the type designation AK210W.
