GB/T 12224 Ceramic Valve

A GB/T 12224 ceramic valve is a highly durable, wear-resistant isolation and control valve manufactured, dimensioned, and pressure-tested in strict compliance with the Chinese national standard GB/T 12224, featuring internal flow-control elements (such as the ball, seat, or disc) crafted from structural engineering ceramics like zirconia (ZrO2​) or alumina (Al2​O3​). While the outer pressure-retaining body is cast or forged from heavy-duty steel to absorb mechanical piping stresses, the solid ceramic lining achieves near-diamond surface hardness and absolute chemical inertness. Conforming to standard structural and test metrics, these extreme-service valves are primary specifications in coal-fired power plants, flue-gas desulfurization (FGD) loops, mineral tailings lines, and corrosive chemical delivery systems handling highly abrasive media. Slurry pipeline contractors and mineral processing engineers can eliminate erosive wear failures and extend valve service life by importing certified GB/T 12224 ceramic valves directly from leading manufacturers in China via our advanced B2B digital marketplace.
