ARC Valve

ARC Valve manufacturer, factory and supplier in China. The automatic recirculation or minimum flow valve is a special form of lift check valve installed downstream of boiler feed pumps. It ensures a minimum flow rate in the event of low flow operation. 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.
