The non-return valve (NRV) is typically located on the discharge side of a pump, between the pump outlet and the pipeline. Its primary function is to prevent backflow, ensuring that fluid only moves in one direction—away from the pump. This placement helps maintain system pressure and protects the pump from potential damage caused by reverse flow.

How does an auto recirculating valve operate?
Auto recirculation valve is used to ensure a minimum flow is maintained through the pump all the time. Recirculation valves are mostly combined with Non Return Valves in the main flow pipe , when flow is established through the discharge line which means that the NRV is open , recirculation valve is closed through a mechanical linkage between the NRV and recirculation valve . Usually the recirculation valves develops passing through it after a period of time due to wear out in the contact points between the NRV and recirculation linkages.
