Lug-type butterfly valves for gas: DVGW certified
The AK211G is a concentric butterfly valve that is designed for gas applications. The body is made of epoxy-coated GGG40, the disc is made of stainless steel 1.4408 (CF8M) or GGG40 (EN GJS 400-15) and the seat ring is made of NBR. This butterfly valve is certified according to DVGW-Gas and is suitable for fuel gas according to G 260 (-20°C to max. +60°C). 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 AK211G is also deliverable as a wafer type, it is called AK210G then.
