In the valve industry, tungsten carbide ball and plug valve are two common opening and closing devices, although they are both used to control the on/off of fluids, there are obvious differences in structure, function and application scenarios.
Tungsten carbide valve ball, as the core component of ball valve, its structure is relatively simple. It is usually a ball made of carbide that opens and closes by rotating 90° around the axis of the stem. This design makes the carbide valve ball have the advantages of small flow resistance and fast opening and closing. The plug valve uses a plug body with a through hole as the opening and closing parts, and the plug body rotates with the valve stem to achieve the opening and closing action. The plug body of the plug valve is mostly a cone or a cylinder, which is matched with the conical orifice surface of the valve body to form a sealing pair.
Due to the particularity of its material, the tungsten carbide valve ball has excellent wear resistance and corrosion resistance, and can maintain stable performance in harsh environments such as high temperature and high pressure. At the same time, the carbide valve ball has small flow resistance and fast opening and closing, which is especially suitable for occasions that need to quickly cut off the fluid. The plug valve has the characteristics of simple structure, rapid opening and closing, and low fluid resistance, and can quickly connect or cut off the pipeline in emergency conditions such as accidents. Compared with gate valves and globe valves, plug valves are more flexible in operation and faster in switching.
Because of its excellent performance, tungsten carbide valve balls are widely used in pipeline systems in petroleum, chemical, electric power and other industries, especially in the occasions that require frequent opening and closing and adjusting the flow rate. The plug valve is more used in the medium with low temperature and high viscosity and the parts that require fast switching, such as urban water supply, sewage treatment and other fields.
