The recirculation valve is used for the automatic recirculation of the minimum flow of the centrifugal pump to prevent the damage of the centrifugal pump due to overheating, noise and vibration under low load. The recirculation valve is used to control the return flow. When the flow of the pump decreases, the outlet pressure of the pump increases, the bypass opening increases and the return flow increases, so as to ensure that the flow of the pump is always greater than the minimum continuous flow.
