What does a cab suspension levelling valve do?

This cab suspension levelling valve plays a critical role in maintaining the stable position of the driver's cabin through pneumatic regulation. By monitoring the height of the cab, it manages air pressure to compensate for varying loads, ensuring a smooth ride and reducing structural vibration during transit.
