Metal Seated Lug Style Option

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 metal-lined (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 double-shaft seals and body bushings to assure smooth, low-torque operation. They are available with a full range of pneumatic, electric, and hydraulic actuation.


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. 

Features

  • 100% bubble-tight positive shutoff
  • Full-rated bi-directional shutoff
  • Field replaceable resilient seat
  • Non-wetted body body designs
  • Wide selection of materials available
