API 609 Category B Soft Seated
Butterfly Valve, EN 593, ASTM A351 CF8, Double Eccentric.
Valve Description
Compared to other valve types, Bosseal high-performance butterfly valves offer clear advantages in cost and space savings, along with a broader size range. The faster operation, combined with minimal friction and wear between the disc and seat sealing surface, ensures longer cycling life and reduces the total cost of ownership. The double-offset design further enhances durability, lowers torque, and makes the valve ideal for frequent operation. Bosseal high-performance butterfly valves have successfully passed a million-cycle test, demonstrating their reliability and efficiency.
