Automatic recirculation valve ARV or ARC Valve Pump ...

An automatic recirculation valve is a kind of pump protection device. It automatically protects the centrifugal pump when a pump body occurs cavitation damage or unstable (especially conveying hot water at low load operation). Once pump flow is lower than the preset flow, bypass can completely open to ensure the minimum required flow pump.

Jul 20, 2019  Automatic recirculation valve works to protect the pump. However, if there is no adequate fluid, and the automatic valve fails to control the flow of the liquid, there is a pressure build-up in the pump. When the reverse flow of fluid occurs, the speed of the pump is affected. It leads to a slowing of the impellor.
