The OpDX High Performance Butterfly Valve uses a pressure-assisted seating concept to achieve bi-directional bubble-tight shutoff while maintaining a low breakout torque requirement. Available in ANSI Class 150 to 600 and 2” to 36”, the OpDX has a characterized disc enabling throttling.

• • Metal & Soft Seating Available
  • Available in metal (ANSI Class IV) or soft seat (ANSI Class VI)
  • Eccentric disc lifts off of the seat to prevent wear
  • Accurate throttling achieved with modified parabolic geometry machined into the seat
  • Rugged and lightweight flangeless wafer body
  • MSS SP-67 face-to-face permits shorter flange bolting than ball or eccentric plug valves, increasing safety and reducing possibility of leakage
