The turbine butterfly valve in aluminium alloy compressed air pipeline is a specially designed butterfly valve, which uses the turbine mechanism to achieve the opening and closing of the valve. The main feature of the turbine butterfly valve is that by turning the handwheel or handle, the turbine (worm gear) device is driven to rotate, which in turn controls the movement of the valve stem, causing the butterfly plate to rotate inside the valve body to regulate or cut off the fluid. Aluminium alloy turbine butterfly valve has many advantages, such as compact structure, light weight, small operating torque, rapid opening and closing. Due to the use of aluminium alloy material, it also has excellent corrosion resistance and long service life. In addition, the turbo butterfly valve has good sealing performance, which can effectively prevent the leakage of fluid in the pipeline. In the compressed air pipeline system, aluminium alloy turbo butterfly valve is commonly used to control the flow of compressed air and cut off the air source. It is suitable for a variety of working conditions, such as high temperature, high pressure, corrosive media, etc. It is widely used in chemical, petroleum, light industry, food and other fields. By adjusting the opening degree of the turbine butterfly valve, it can achieve precise control of compressed air flow to meet the needs of different processes.
