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