ASTM A105N Butterfly Valve

An ASTM A105N butterfly valve is a high-pressure, quarter-turn rotary valve featuring a body forged from normalized carbon steel (ASTM A105N), which exhibits superior impact toughness and mechanical ductility under extreme low-temperature and high-stress operations. Available in double-offset (high-performance) or triple-offset (zero-leakage) configurations, the valve uses a rotating disc mounted on a heavy-duty shaft to isolate or modulate flow with low torque demands and a highly compact face-to-face profile. The normalization heat-treatment of the A105 steel ensures a uniform grain structure, making it ideal for elevated pressure ratings in steam, oil, gas, and chemical lines. Refinery piping engineers, district heating contractors, and terminal managers can reduce line weight and piping footprints while ensuring high-pressure safety by importing certified ASTM A105N butterfly valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
