The mining industry including 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 valve should be wear-resistant, corrosion resistant, and excellent in circulation performance when selecting the valve. KOSEN production includes knife gates, metal seated ball, double/triple off-set butterfly and angle valves, which are generally made of cast iron, carbon steel, stainless steel, Harris alloy and titanium.
