Flanged Butterfly Valve: Flanged Valves

The AK211 is our new concentric flanged butterfly valve for the highest demands, as the AK211 is almost completely configurable. Each AK211 flanged valve is assembled specifically to your requirements, with exactly the materials you need for your specific application. In addition to the standard body and disc materials, the AK211 is also available in special materials. The valve seal, known as the seat ring or sleeve, is also available in many different rubber types. The AK211 is also DVGW Gas (AK211G) and DVGW Drinking Water (AK211W) certified. All valves from FERGO Armaturen GmbH can be easily automated with various actuators thanks to the standardized (EN ISO 5211) mounting flange; we are also happy to handle this for you. The AK211 is also available as a wafer version and then has the type designation AK210.

In addition to the standard EPDM, NBR, and Viton/FPM/FKM seats, our flanged AK211 can also be ordered with various food-grade seats, high-temperature/low-temperature seats, silicone, Flucast, Hypalon, Butyl, and many others. The butterfly valve with ATEX is also available upon request.

The AK211 and AK210 can be perfectly tailored to your application—ask one of our consultants which combination is ideal for you—completely non-binding and free of charge, of course.
