Introduction of Double Eccentric Butterfly Valve

Offering significant cost and space savings compared to other valve types, the double eccentric butterfly valve features a larger size range and faster operation. Its design minimizes restriction and wear between the disc and seat sealing surfaces, ensuring a longer cycle life and reduced total cost of ownership. With its two offsets, the valve delivers extended durability and lower torque, making it ideal for frequent use. The Bosseal high-performance butterfly valve has successfully passed a million-cycle test.
