Every engineer encounters the challenge of having to choose one technology over another. A notable example is specifying the valve solution for a given process line. Sometimes the choice is evident. Other times, it is a tight horse race of options. In light of that, in this article, I want to focus on a topic I frequently get asked about: the differences between floating and trunnion-mounted ball valves. Selecting the most valve of the two for a specific service could be tricky at times. Thus, knowing what sets them apart helps a long way. Read on to learn about both valve solutions. My goal is to lead you to identify which design is more appropriate.
