Soaring demand for wear-resistant valves in coal chemical industry; ceramic slag lock valves & metal hard-seated ball valves become standard equipment for gasification units

With the launch of multiple large-scale coal-to-oil and coal-to-olefin projects nationwide, demand for heavy-duty wear-resistant valves for gasification and slag treatment systems keeps rising. Industrial surveys show that ceramic slag lock valves and ceramic ash removal ball valves for pulverized coal delivery have been adopted by 71% of black water and slag discharge units in large coal gasification plants. Conventional alloy valves serve less than half a year under high particle erosion conditions. Domestic ceramic-lined ball valves with metal scraper hard seals can operate stably for more than 3 consecutive years, cutting overall procurement costs by 40% compared with imported alternatives. They have become mainstream products for major coal chemical bases such as Ningdong and Luxi.
