Triple Eccentric Butterfly Valve
A triple eccentric butterfly valve is used for shut-off as well as regulating duty applications.
TECHNICAL DESCRIPTION:
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.
SPECIAL FEATURES
- These valves are provided with metal-to-metal (laminar) seals.
- The triple eccentric butterfly valve has the unique feature of zero friction between the valve seal and seat with very low operating torque.
- Steam jacketed offset butterfly valve option is available for all tail gas applications and for high Sulphur gas lines.
