Symbols are showing the internal function of the levelling valve, with restrictions inside, the reaction will be progressive (increase lateral stability for road vehicle), whereas without restrictions the time to inflate the bellows will be shorter (container trailer, tipper), see also Type charts below.

The Type chart shows the air flow depending the angle of the lever. The higher the type number is (internal diameter of the valve) the higher air flow rate is reached. The curve profil is also important, as they are more or less progressive in the range 0° to 15° angle.
