ASTM A217 WC6 Butterfly Valve

An ASTM A217 WC6 butterfly valve is a highly engineered, high-temperature rotary valve cast from premium chrome-moly alloy steel to provide reliable isolation and throttling control in high-heat utility systems. The WC6 chemical composition is enriched with chromium and molybdenum (1.25% Cr, 0.5% Mo), providing the valve shell and disc with exceptional creep resistance, structural stability, and oxidation immunity at continuous operating temperatures up to 593°C. Featuring a high-performance triple-offset design with a metal-to-metal sealing boundary, the valve eliminates seating friction and ensures bubble-tight shutoff across its 90-degree operating radius. Refinery maintenance teams and thermal power piping engineers can secure absolute high-heat reliability and eliminate elastomer thermal failure by importing certified ASTM A217 WC6 butterfly valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
