Natural gas high-pressure ball valves are often used to cut off or connect media in oil, natural gas, coal and ore mining, refining and processing, and pipeline transportation systems. Special ball valve and ash unloading valve for pulverized coal injection are especially suitable for blast furnace pulverized coal injection, dust and solid powder pipeline systems, air pipelines and spray gun pipelines. The natural gas high-pressure ball valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as frictionless switch, non-wearing seal, and small opening and closing torque. This can reduce the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and close shut-off of the medium. It is widely used in petroleum, chemical, urban water supply and drainage and other working conditions that require strict cut-off. The manual ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. The ball valve is a new type of valve that has been widely used in recent years.
