The working principle of pneumatic butterfly valve is according to the main control Industrial Valves opening and closing of the rotation of the valve, the main of fluid in pipe system to intercept connection and distribution function. Pneumatic butterfly valve by pneumatic device and the combination of a valve, control precision, switch easily, flexible operation etc. , are widely used in the pipe system in the field. Pneumatic butterfly valve D641X samples figure

pneumatic butterfly Industrial Valves type due to different design of pneumatic butterfly valve has a lot of kinds, functional diversity. Pneumatic butterfly valve type is commonly: D671X - Pneumatic butterfly Industrial Valves to the clamp, D643X - 10/16 10/16 q flange soft seal eccentric butterfly valve, pneumatic D643H - 10/16/25 / c pneumatic hard seal eccentric butterfly valve, D641X - 40 10/16 q flange sealing center line butterfly valve, pneumatic with a small flow resistance, strong control, and other common characteristics of small volume, simple structure, for the pipeline system provides a variety of choices, make piping transportation more convenient, promote the common development of the piping and valves.
need huge investment, so it is important to shop with caution.
