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.
EGR (Exhaust Gas Recirculation) look for it to be attached to the exhaust manifold or a pipe from the exhaust manifold
Exhaust Gas Recirculation. A small amount of exhaust gas is fed back into the cylinder to lower combustion temperatures and lower tail pipe emissions.

Yes, deionized (DI) water can be kept under recirculation to maintain its purity. Recirculation helps prevent contamination by keeping the water flowing and ensuring that it remains clean and free of impurities for longer periods. Regular monitoring and maintenance of the recirculation system are necessary to ensure its effectiveness in preserving the quality of the DI water.

Because your process have differents points of operation (flows, pressures) and the pump only one point (intersection curves process and HD pump). We can have others scenarios with a recirculation pipe and control valve.
P0400 - Exhaust Gas Recirculation Flow Malfunction Possible causes - Exhaust Gas Recirculation (EGR) solenoid valve harness is open or shorted - Exhaust Gas Recirculation (EGR) solenoid valve circuit poor electrical connection - Exhaust Gas Recirculation (EGR) volume control valve stuck closed - Faulty Exhaust Gas Recirculation (EGR) volume control solenoid valve - Dead (Weak) battery - Faulty EGR temperature sensor and circuit - Faulty EGR Valve
