Double Eccentric Design Offset Disc Butterfly Valve

Double-eccentric butterfly valves are industrial valves designed to open or close a passage of the working medium fully flowing via a pipeline. They can also be used for flow-control purposes. However, a 100% tightness of the valve cannot be guaranteed in long-term use for control purposes.

Where are double eccentric butterfly valves used?

Double eccentric butterfly valves are often used in water supply applications below ground as an alternative to gate valves. When installing butterfly valves below ground, a lower ground depth is required, and they are typically more cost-effective, especially in large dimensions, compared to gate valves. Of course, they can also be used above ground.
