Leveling Valve

Filter
Purpose: To control the pressure in the air suspen- sion bellows in proportion to the vehicle load. Some Levelling Valves has an additional 3/2 directional control valve which closes from a pre-defined, adjustable lever angle and which takes on an exhaust function when the lever is moved further. This "height limitation" prevents the vehicle being raised above the permissible level by means of the raise/lower valve.
