ASTM A351 CF3 Butterfly Valve

An ASTM A351 CF3 butterfly valve is a compact, high-efficiency quarter-turn rotary valve cast from low-carbon 304L stainless steel, designed for space-saving fluid isolation and throttling in corrosive environments. Featuring a slim wafer, lug, or flanged body, the valve controls line media via a centrally pinned or eccentric-offset disc that rotates 90 degrees on its vertical axis. The CF3 metallurgy prevents weld-zone sensitization and intergranular corrosion, making it highly reliable in applications requiring frequent pipe welding or modification. Piping layout contractors and chemical plant operators can optimize pipeline weight footprints and eliminate weld-zone corrosion by sourcing certified ASTM A351 CF3 butterfly valves straight from premier manufacturers in China via our advanced B2B commercial platform.
