SUL - Automatic Recirculation Valve

The SCHROEDAHL Automatic Recirculation Valve of SUL series is used for the pump protection of centrifugal pumps.

SCHROEDAHL is the largest supplier of Automatic Recirculation Valves in the world. These ARVs, or pump protection systems, are our principal products.

Our ARV is a high quality automatic solution to protect centrifugal
pumps against overheating, instability and cavitation, during zero process flow and low load conditions. If the flow through the system is or falls below a certain level, the bypass system opens automatically and the fluid is recirculated, providing the required minimum flow for the pump.

Special operation requirements, low load cases, complicated commissioning situations and the pressure in the bypass line have an impact on the valve design and therefore are typically part of customers RFQ information - SCHROEDAHL can offer solutions at a very high level.
