Application of Butterfly Valve Double Eccentric

Butterfly Valve Double Eccentrics are most commonly used in underground water supply applications as an alternative to gate valves. When installing butterfly valves underground, lower burial depths are required, and they are generally more cost-effective than gate valves, especially at larger sizes. They can of course also be used on the ground.
