Double Eccentric Butterfly Valve
- A double eccentric butterfly valve can be used in shut-off applications of air, gas, and water/liquid lines.
- 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.
