Double Eccentric Butterfly Valve Introduction
The double eccentric butterfly valve stands out for its cost and space efficiency, offering a larger size range compared to other valve types. Its design allows for faster operation and minimizes restrictions and wear between the disc and seat sealing surface. This results in a longer service life and reduced total cost of ownership. The two offsets in the valve contribute to its durability and lower torque requirements, making it ideal for frequent operation. The Bosseal high-performance butterfly valve has successfully passed a million-cycle test, demonstrating its exceptional reliability and longevity.
