metallined (Series M200) configurations. All Series 200 butterfly valves feature a unique angle disc that creates a 360° uninterrupted differential sealing surface.

Series 200 butterfly valves have independent flange seals and a non-wetted body that may be specified with either lug or wafer design. All Series 200 butterfly valves
are easily repaired in the field.
