ASTM A351 CN7M Globe Valve

An ASTM A351 CN7M globe valve is a linear-motion flow regulating valve cast from Grade CN7M alloy (Alloy 20), designed specifically to provide precise throttling and isolation in hot, aggressive sulfuric acid and severe chemical environments. The nickel-chromium-copper-molybdenum formulation of CN7M offers outstanding resistance to localized pitting, crevice attack, and stress corrosion cracking across varying acid concentrations and elevated temperatures. Conforming to standards like API 623, ASME B16.34, and BS 1873, these chemical-grade globe valves are critical specifications in chemical fertilizer production, synthetic fiber processing, and acid recovery plants, allowing process engineers to achieve precise flow regulation without suffering body degradation by importing certified ASTM A351 CN7M globe valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
