ANSI B16.34 Butterfly Valve

An ANSI B16.34 butterfly valve is a quarter-turn rotary valve engineered, calculated, and pressure-tested in full accordance with ASME/ANSI B16.34 standards for pressure-containing metallic valves. Available in double-offset or triple-offset high-performance geometries with metallic or soft seating, it delivers bubble-tight bi-directional isolation and modulating flow control across standard ANSI pressure classes (Class 150 to Class 600). Conforming to complementary benchmarks like API 609 and ISO 5752, these high-integrity rotary valves are primary specifications in petroleum refining, chemical processing facilities, and offshore gas platforms, allowing piping designers to guarantee standardized wall thickness and shell pressure safety by importing certified ANSI B16.34 butterfly valves directly from leading manufacturers in China via our advanced B2B commercial platform.
