What is an automatic recirculation valve

The automatic recirculation valve (ARC valve\ARV valve) is a multifunctional valve whose main function is to ensure that the predetermined minimum flow rate is always obtained through the centrifugal pump. This is very important, because centrifugal pumps will experience overheating and cavitation, which can cause permanent damage if they run dry.

 Automatic Recirculation Valve - Purpose & Function

Automatic recirculation valves, sometimes referred to as pump protection valves or minimum flow valves are installed on the outlet of a centrifugal pump discharge line. Their purpose is to prevent the pump from overheating by ensuring that there is a minimum flow through the pump at all times. They have replaced traditional multi valve pump protection solutions. T AR Valve unites three important functions of a pump protection system:

  • a non return function in the main line, that prevents medium flowing backwards to the pump
  • automatic bypass control, that ensures that a minimum flow is allowed to return to the pump in low demand periods
  • pressure letdown functionality, that ensures that the recirculating medium is kept at the correct pressure and flashing and cavitation are avoided
Frequently Asked Question

Do you have any question?

Automatic recirculation valves, sometimes referred to as pump protection valves or minimum flow valves are installed on the outlet of a centrifugal pump discharge line. Their purpose is to prevent the pump from overheating by ensuring that there is a minimum flow through the pump at all times.

An automatic recirculation 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 over heating and cavitation and can be permanently damaged if they run dry.

If a high pressure pump is deadheaded, significant damage results for the pump or the system.Recirculation lines provide a means of relief for high pressure pumps when operated against a closed valve or other system obstruction.
