Strict analysis of molten steel to ensure that the material is pure and free of impurities, laying a solid foundation for high-quality valves. When the furnace is opened, the sparks are splashed, and the high temperature molten steel is accurately cast, and every inch is condensed with ingenuity. Wanxin adopts advanced casting process to ensure strong valve structure and excellent sealing performance. From molten steel analysis to open-hearth casting, Wanxin valves create safety guards for industrial fluid control with superb skills.
