Feature:
1. Triple Offset or Concentric Lining Type
2. Low friction between seat and disc
3. Zero leakage sealing design
4. One piece shaft
5. Metal to Metal sealing
6. Low torque for compact actuators and long cycle life
7. Blow-out proof stem
8. Extended stem can be selected
9. Locking device can be selected
10. Triple eccentric butterfly valves provide performance reliability and quality for critical process applications, steam isolation, and extreme temperature conditions
11. A two-way zero leakage closure with a metal seat provides sealing integrity that was previously associated only with soft seated valves, even after a long cycle
12. Low torque for quarter turn operation allows for smaller actuators and lower costs
13. Its compact design makes installation easier because the valve is lighter and requires less pipe support
14. Triple offset butterfly valve can reduce weight and space and save a lot of costCustomized Butterfly Valve
