ARC Valve

Automatic Recirculation Valves(ARC valve) is a kind of pump protection device. It automatic protect centrifugal pump when pump body occur cavitation damage or unstable (especially conveying hot water at low load operation medium). Modern industrial equipment process request centrifugal pump are basically work under condition of variable flow.
An Automatic Recirculation Valves (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.
