What are ARV or ARC valves

ARV valve stands for Automatic Recirculation Valve. An automatic recirculation 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 over heating and cavitation and can be permanently damaged if they run dry.

ARC valve is the abbreviation for Automatic Recirculation Control valve, and ARC® is a registered name of Yarway. The function of this valve is the same as that of a AR valve.

Solution for pump protection

Modern industrial equipment process request centrifugal pump are basically work under condition of variable flow. 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.
