Triple Offset Metal Seated Butterfly Valve

Triple Offset Metal Seat Butterfly Valve is used to prevent galling and scratches between the metal seat and the metal disc due to its unique design. The only time where the seal comes into contact with the seat is at the point of complete closure.

Series - 150 To 600

Triple offset valves are generally used in applications which require bi-directional tight shut-off in oil and gas, LNG/NPG terminal and tanks, chemical factories, and shipbuilding. They are also used for dirty/heavy oil to prevent extrusion.

Design Features
  • Triple offset structure, single or bi-directional seal
  • Low friction between seat and disc of valve
  • “Zero leakage” Sealing design
  • One piece shaft
  • Low torque enables the compact actuator and a long cycle life
  • Blow-out proof shaft
