Introduction to Double Eccentric Butterfly Valve

Compared to other valve types, the double eccentric butterfly valve offers significant cost and space savings, with a wider size range. Its faster operation and reduced wear between the disc and seat sealing surface ensure a longer cycling life and lower total cost of ownership. The two offsets provide extended durability, lower torque, and make the valve ideal for frequent operation. Bosseal high-performance butterfly valves have successfully passed a million-cycle test, guaranteeing reliability and long-term performance in demanding applications.
