Product Summary

Recirculation Valves automatically protect centrifugal pumps during low load operation. As the pump's load drops below a preset flow rate, the valve's disc moves towards its seat and causes the bypass bush to open a bypass flow path. The pump minimum flow rate is thus reached and maintained. A common application of recirculation valve is for pumps which handle hot water for boiler feeding or cooling water plants, where partial evapouration of the water content might otherwise cause the pump to run dry. Even when the flow rate through the main valve to the boiler is completely shut off, a minimum flow is maintained. Another application is to protect high performance pumps during a start up phase. In this scenario, several pumps are used in parallel with one in stand-by. The pump recirculation valve enables the swap out to occur without damage to the pumps. Recirculation valve is widely used in the Power, Paper and Pulp Maritime, Refining and Chemical industries.
