Mining & Metallurgy

The mining & metallurgy (beneficiation + smelting) has a high demand of severe service valves in mineral, and smelting processes. 

The medium usually has characteristics of large particles, high hardness, high viscosity, strong acid and strong alkali, etc. 

The valves should be wear-resistant, corrosion resistant, and excellent in circulation performance. Yaao Valve produces knife gates, metal seated ball, double/triple off-set butterfly and angle valves in carbon steel, stainless steel, Harris alloy and titanium suitable for mining industry.
