FBO asserts itself as being in charge of functions as security and comfort, such as the pneumatic suspension regulation. |
|
| Levelling valve |
| It makes it possible to maintain a constant distance between the bogie and the vehicle body, whatever the load of the body is, by regulating the pressure in the suspension cushions. |
| Security valve |
| It makes it possible the quickly discharging of the suspension cushions, in case of problems with a suspension item, when the distance bogie / body is too important. |
|
Differential valve |
| In case the pressure in one air spring is too low, this valve allows the other air spring to discharge by connecting them together. |
