Wafer Butterfly Valve

The AK200 butterfly valve is a wafer-type version of our successful AK201 (lug-type). The AK200 and AK201 offer good quality at a low budget price, and they have been used successfully for standard applications for years. Of course, the AK200 is available in different types. The body is made from ductile iron GGG40 and the disc is from stainless steel. The seat rings can be delivered in NBR, EPDM, and FKM (Viton). Due to the ISO5211-top mounting flange, you can choose your actuation: lever, hand wheel with gear, electric, pneumatic single, or double acting. FERGO Armaturen GmbH offers a wide range of different butterfly valves. Just contact one of our consultants to get the right type for you.
