This beginner-friendly guide explains what an Automatic Recirculation Valve (ARV) is, why it’s important, and how it works. It shows how ARVs protect centrifugal pumps from damage caused by low flow conditions—such as overheating, cavitation, vibration, and seal failure—by diverting some fluid back to the source when demand drops below a safe threshold. https://indibloghub.com/post/what-is-an-automatic-recirculation-valve-a-complete-beginner-s-guide
