5. Selection of pneumatic ball valve is more critical than calculation
Calculation and selection are relatively more critical and complicated. Since the calculation is only a simple formula, it does not depend on the accuracy of the formula calculation, but depends on whether the main parameters of the given processing technology are accurate. Model selection involves a lot of content, and a little carelessness will lead to poor model selection, which not only leads to waste of human resources, human and material resources, and capital, but also the actual application effect is not ideal, resulting in many application problems, such as credibility, service life, operation quality, etc.

During the operation of pneumatic butterfly valve, due to its simple structure, small size, light weight, and relatively small number of components, the operation is relatively simple, and has good controllability. For some large industries, it is a great advantage, because it can filter and control the fluid characteristics.
