Double Eccentric Butterfly Valve Introduction
The Double Eccentric Butterfly Valve offers significant advantages over other valve types, including cost savings, space efficiency, and a broader size range. Its design features faster operation and reduced friction and wear between the disc and seat sealing surfaces, which contributes to an extended service life and lower total cost of ownership.
The valve's two-offset design enhances its durability, reduces operating torque, and makes it ideal for frequent use. Bosseal’s high-performance butterfly valves have been rigorously tested and proven to withstand over a million cycles.
