This double excentric highperformance butterfly valve provides important advantages:

1. 360° sealing seat area
2. Long life of seat due to early disengagement of the disc from seat
3. Reduced torque figures compared to conventional butterfly valve designs
4. large diameter shaft which provides a direct and distortion free power transmission to disc and therefore excellent control characteristics (low hysteresis)
