Key Specifications / Features
As a factory in China specializing in double-offset butterfly valves, we offer robust solutions crafted from ASTM B148 C95800 aluminum bronze. Our 14-inches valves meet EN 593 and API 609 standards, featuring a double eccentric design for enhanced performance. Rated at 150 LB, they come with a 17-4PH stem and wafer end for reliable operation. Designed for long service life and frequent cycling, these valves ensure lower torque, tight sealing, and excellent control characteristics. They offer bi-directional sealing under full pressure and are available with a fire-safe seat option.

Butterfly Valve, EN 593, 14 Inch/DN350, 150 LB, Double Offset.
Valve Description
Compared to other valve types, double eccentric butterfly valves offer clear advantages in cost efficiency, space savings, and a wider size range. They provide faster operation with less restriction and reduced wear between the disc and seat, ensuring a longer service life and lower total cost of ownership. The two-offset design allows for extended valve life, lower torque, and suitability for frequent operation. Bosseal's high-performance butterfly valves have successfully passed a million-cycle test, demonstrating exceptional durability.
