Schroedahl - Model SUL Series -Automatic Recirculation Valve

Modern processing industry often requires centrifugal pumps to operate with fluctuating flows. This is because of automated control of such processes. When flows are too low in centrifugal pumps, however, this may result in overheating and lead to damage or cause unstable operation. It is important that flows through a pump do not fall below a certain minimum as stated by the pump manufacturer. The SUL valve is a reliable and economic solution.
