Can a butterfly valve be used effectively for flow regulation?

A butterfly valve is generally not the ideal choice for effective flow regulation due to its design and operating principles. While it can control flow to some extent, it is primarily intended for on/off services. The disc element in a butterfly valve, when partially opened, creates turbulence and can lead to cavitation and erosion issues, ultimately affecting its performance.

For accurate flow control and regulation, other types of valves, such as globe valves or control valves, are preferable. These designs allow for more precise adjustments and a higher degree of control over flow rates.

In summary, while a butterfly valve can be used for flow regulation in certain circumstances, it is not built to excel at this function, which supports the assertion that it does not serve well for effective flow regulation. This makes the claim that it cannot be used for regulation valid in general practice.
