Introduction of Double Eccentric Butterfly Valve

This valve offers significant cost and space savings compared to other valve types, with a broader size range, faster operation, and reduced restriction and wear between the disc and seat sealing surfaces. These features contribute to a longer service life and lower total cost of ownership. With its two-offset design, the valve provides extended durability and lower torque, making it ideal for frequent operation. Bosseal's high-performance butterfly valve has successfully passed a million-cycle test.
