Double Eccentric Butterfly Valve
A double eccentric butterfly valve can be used in shut-off applications of air, gas, and water/liquid lines.
TECHNICAL DESCRIPTION:
The valve mainly consists of the body, disc, trunnion, shaft, stuffing box, gearbox, bearings and drive
mechanism. The valve has an eccentricity of the drive shaft in two axes, why it is called a double
eccentric butterfly valve. Due to this construction, the valve provides high torque with leakproof sealing.
SPECIAL FEATURES
- Special sealing geometry and seal shape ensure zero leakage and free movement of the disc for more than 95% of travel.
- In situ seal change possibility
