SCHROEDAHL is the largest supplier of Automatic Recirculation Valves (ARV) in the world. 

The SCHROEDAHL ARV provides an automatic solution to protect centrifugal pumps against overheating, instability, and cavitation under no, or low process volume conditions.  As soon as the flow rate of the process falls below a certain value, the bypass opens, delivering the minimum flow required for the pump.
