Double Eccentric Butterfly Valve

A double eccentric butterfly valve consists of a circular disc pivoted on an offset axis within a pipe. Unlike concentric or single eccentric valves where the disc rotates around an axis aligned or slightly off-center from the pipe’s centerline, respectively, a double eccentric flanged butterfly valve‘s disc is displaced both axially and radially. This dual offset creates two points of eccentricity, hence the name.

Structure

Double eccentric butterfly valve structure consists of several key components that work together to regulate the flow effectively. Here is a brief introduction to the structure of a double eccentric butterfly valve:

1. Body: The body of the double eccentric butterfly valve china serves as the outer casing that houses the internal components and connects to the pipeline.
2. Disc: The disc, also known as the butterfly, is a critical component of the valve responsible for regulating the flow of fluid.
3. Shaft: The shaft connects the actuator to the disc and transmits the torque required to rotate the disc within the valve.
4. Seat: The seat forms a seal around the disc when the valve is closed, preventing any leakage of the fluid.
5. Actuator: The actuator is the mechanism that controls the movement of the disc within the valve.
