Triple Offset Metal Seated Pneumatic Operated Butterfly Valve
Introductions
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.
Features
- Frictionless closure
- Super long usage life
- Double block and bleed
- Blowout-proof stem
- ISO 5211 top flange
- Fire safe design
- Optional stellited seated
