Norriseal Series 200 butterfly valves provide bi-directional, positive shutoff to 200 psig working pressure. They are available in both resilient-seated (Series R200) and 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.
