Mining and metallurgy present significant challenges. In ore extraction, precious metal and steel processing, equipment must endure the transport of corrosive and hazardous substances, with each component required to have high safety and durability. Harsh environmental conditions demand components that can withstand seawater, acid solutions, and varying material concentrations. Electrolytic processes require materials to meet high chemical standards due to the acids used. Steel pickling involves handling corrosive chemicals, high temperatures, and high solid content. Acid regeneration processes impose strict requirements on material heat and chemical resistance. YNTO control valves demonstrate their advantages in these processes, ensuring reliability and performance.
