The flow management valve is a part of the ORVR system This plastic valve is placed inline between the fuel tank vent fitting and the EVAP canister. It
is located on top of the fuel tank.
The flow management valve is one of the components used in the ORVR system. The valve meters the flow of fuel vapors to the EVAP canister during
vehicle run and refueling. Pressure from the tank during refueling opens the main port valve and allows vapors to enter the EVAP canister. During
vehicle run, the vapors are metered through an orifice to the EVAP canister. It is also used as a liquid separator to keep liquid fuel out of the EVAP
canister.
