Design standard:ASME B16.34 All the Automatic Recirculation Valve (Pump protection Valve) (ARV) (Pump protection Valve) supplied by SSIE are 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). Once pump flow is lower than the pre-set flow, bypass can completely open to ensure the minimum required flow pump. Even running fully closed, namely running flow is zero, the minimum flow can also pass bypass for Automatic Recycle. Pressure reduced through the multistage bypass pressure reducing valve
