ASTM A217 C12A Gate Valve

An ASTM A217 C12A gate valve is a heavy-duty, linear-motion isolation valve cast from 9% chromium, 1% molybdenum vanadium-modified alloy steel (Grade C12A), engineered for exceptional creep rupture strength and oxidation resistance in ultra-high-temperature systems. This specialized creep-resistant alloy enables the valve body to withstand continuous, severe operating conditions up to 650°C (1200°F) without structural degradation or thermal deformation. Featuring a bolted or pressure-seal bonnet and a rising stem, the valve drives a flexible or rigid wedge down to achieve a leak-tight metal-to-metal seal while providing an unobstructed, straight-through path when fully open. Power plant engineers and project procurement networks can ensure long-term creep resistance and optimal high-temperature isolation by importing certified ASTM A217 C12A gate valves directly from premier manufacturers in China via our advanced B2B digital marketplace.
