Introduction of Double Eccentric Butterfly Valve
Compared to other valve types, double eccentric butterfly valves offer clear advantages in cost efficiency, space savings, and a wider size range. They provide faster operation with less restriction and reduced wear between the disc and seat, ensuring a longer service life and lower total cost of ownership. The two-offset design allows for extended valve life, lower torque, and suitability for frequent operation. Bosseal's high-performance butterfly valves have successfully passed a million-cycle test, demonstrating exceptional durability.
