Why choose carbon steel welded ball valves
Recently, in the packaging workshop of Jinbin, large-diameter welding ball valve has been placed. These ball valves are all made of Q235B material and equipped with handwheel devices. The welds are beautiful and uniform, with zero leakage after testing. The sizes range from DN250 to DN500. Currently, some of them have been produced. 
The large-diameter carbon steel ball valve takes common carbon steel Q235B as the core material and combines the full bore structure advantages of ball valves. It is a universal opening and closing device for medium and low-pressure large-diameter pipelines, suitable for pipelines with a nominal bore of DN300 and above. It takes into account both practicality and economy and is the mainstream choice for the transportation of conventional media in municipal and industrial fields. 
The properties of Q235B low-carbon steel include excellent plasticity and welding performance. Large-diameter valve bodies can be formed by casting or welding. The processing technology is simple, and the manufacturing cost is much lower than that of alloy steel. Later maintenance is convenient. The motorized ball valve adopts a ball rotation opening and closing structure. There is no reduction in the diameter of the passage, and the resistance to medium flow is small. It is easy to open and close and has high operating efficiency under large-diameter working conditions. The sealing surface is equipped with wear-resistant packing, ensuring reliable sealing under normal working conditions. Moreover, the valve body can be treated with anti-corrosion coating on the surface to make up for the general corrosion resistance of Q235B, and is suitable for non-corrosive media.（Carbon Steel Flanged Ball Valve） 
Its specific applications are mainly concentrated in the transportation pipelines of medium and low pressure, large flow rates, and non-corrosive media, with a core application in the urban main water supply network and large pumping stations of municipal water supply and drainage projects. Urban centralized heating and large-scale building HVAC circulating water systems in the HVAC and heating industry; Industrial circulating water and cooling water pipelines in enterprises such as steel, power and chemical industries in the industrial sector, as well as low-pressure transportation pipelines for refined oil products and ordinary oil products; It is also applicable to the opening and closing of large-diameter pipelines and flow regulation of auxiliary media such as low-pressure clean water and gas in industries like metallurgy and mining.
