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.
