API 609 Category B
Butterfly Valve, 8 Inch/DN200, 300 LB, Soft Seat, Double Flanged End.
Valve Description
Double offset butterfly valves are commonly used in pipelines for isolation and regulating applications, particularly where frequent opening and closing are required. Bosseal valves offer several advantages, including zero leakage, low torque operation, a long working life, and low emissions. They provide reliable bi-directional sealing and come with fire-safe features, making them suitable for demanding industrial environments.
