An automatic recirculation valve is a multifunctional valve whose primary purpose is to ensure that a predetermined minimum flow is assured through a centrifugal pump at all times. This is important as centrifugal pumps suffer from overheating and cavitation and can be permanently damaged if they run dry. The automatic recirculation valve offered by us has a unique design whose performance has been perfectly enhanced through simulation and joint research. These valves automatically protect centrifugal pumps during a low load operation. The valve’s disc moves towards its seat and causes the bypass bush to open a bypass flow when the load of the pump drops below a preset flow rate.The most common application of these valves is to protect pumps which handle hot water for boiler feeding or cooling water plants in which partial evaporation of the water content might otherwise cause the pump to run dry. It is widely used in the Power, Paper and Pulp, Maritime, Refining, and Chemical industries.
