Butterfly valve potable water type AK211W

DVGW certified lug-type butterfly valve for drinking water

Butterfly valve: DVGW drinking water certified

The AK211W is a concentric lug-type butterfly valve that is designed for potable water applications. The body is made of epoxy-coated GGG40, the disc is made of stainless steel 1.4408 (CF8M) and the seat ring is made of EPDM. This butterfly valve is certified according to DVGW potable water. All valves of the FERGO Armaturen GmbH are very easy to automate due to the standard top-mounting flange (ISO5211); we can do this for you, too. The AK211W is also deliverable as a wafer type, which is our type AK210W.
