SAFETY VALVE
This valve:
- ventilates the tank
- draws off the fuel vapours
The vacuum in the tank, which could arise when fuel is drawn off is mainly prevented by the ventilation valve set at 0 to 0.020 bars.
If the pressure in the tank exceeds 0.07 to 0.085 bars, the valve will open and for safety reasons a part of the fuel vapour pressure will be discharged to the atmosphere.
