Triple Offset Metal Seated Pneumatic Operated Butterfly Valve




Triple-offset butterfly valves offer the best sealing and longest life of all butterfly valve designs. Here are some of the reasons they are chosen:

  • For the harsh conditions of critical process applications, steam isolation and temperature extremes, TEKO provide performance reliability and quality.
  • The bi-directional zero leakage closure with a metal seat, even after extensive cycling, provides sealing integrity formerly associated only with soft-seated valves.
  • Low torque from quarter-turn action permits smaller actuators and lower cost.
  • Fire-tested designs per API 607, 5th Edition/ISO 10497-5 are available.
  • Compact design means easier installation since valves are lighter and require less pipe ­bracing.




  • Frictionless closure
  • Super long usage life
  • Double block and bleed
  • Blowout-proof stem
  • ISO 5211 top flange
  • Fire safe design
  • Optional stellited seated
