An automatic recirculation valve (ARC valve) is a multifunctional valve whose primary purpose is to ensure that a pre-determined 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.
Through many years of research and development,continuous innovation and practice, Shanghai datian valve Co.Research ZD series Automatic recirculation control
Valve, to prevent overheating, serious noise, unstable and erosion damage of centrifugal pump under low load operation.As long as the flow rate of the pump valve below a certain value, the bypass backflow mouth will automatically open to ensure necessary minimum flow of pump.
