Automatic Recirculation Control Valve

An automatic recirculation control valve, also known as a pump protection valve or minimum flow valve, is installed on the outlet of a centrifugal pump discharge line. Its primary purpose is to prevent the pump from overheating by ensuring a minimum flow through the pump at all times. This valve automatically recirculates a portion of the fluid back to the pump inlet or to a storage tank when the main flow drops below a certain threshold, thus protecting the pump from damage due to low flow conditions and ensuring efficient and safe operation.
