Overview of Double Eccentric Butterfly Valve
The double eccentric butterfly valve stands out for its cost and space efficiency, offering a broader size range compared to other valve types. Its design ensures faster operation with minimal wear between the disc and seat, leading to a longer service life and reduced total cost of ownership. With two offsets, the valve provides enhanced durability, lower torque, and is ideal for frequent use. Bosseal’s high-performance butterfly valves have passed a million-cycle test, ensuring reliable, long-lasting performance in even the most demanding applications.
