Tripple Eccentric Butterfly Valve
- A triple eccentric butterfly valve is used for shut-off as well as regulating duty applications.
- The valve mainly consists of the body, disc, trunnion, shaft, stuffing box, gearbox, bearings, and drive mechanism.
- This valve is similar in construction to a double eccentric butterfly valve with a tilted seat as a third eccentricity.
