The Male-Female Ball Valve for aluminium compressed air pipelines is a special type of valve that is mainly used to control the flow of media in pipelines. The main feature of this type of ball valve is that its connection ports are designed with internal and external filaments. Specifically, the internal wire refers to the internal thread on the inlet or outlet of the ball valve, which is used to connect with the pipeline or connectors with corresponding external threads. External filament, on the other hand, means that some parts of the ball valve (e.g., the connecting flange) have threads on the outside, which can be used to connect with pipes or fittings with internal threads. Male-Female Ball Valves are widely used in aluminium compressed air piping systems because they provide a convenient, fast and reliable connection. In addition, the choice of aluminium alloy material makes the ball valves lightweight and well resistant to corrosion, making them ideal for use in compressed air piping systems. Aluminium Male-Female Ball Valves can effectively control the flow and pressure of the medium and ensure the normal operation of the piping system.
