The invention relates to a leveling valve (101) for discharging and supplying air from and to a plurality of utilization elements (205a,b, comprising a valve disc arrangement (103) for directing air between a source (207) of pressurized air, an exhaust port (3), and said utilization elements, said valve disc arrangement comprising a first and a second valve disc (107, 109), being rotatable with respect to each other such that the valve is switchable between multiple switching positions (105a-e), and wherein in some switching positions either said source (207) of pressurized air or said exhaust port (3) are in fluid communication with said utilization elements. In particular, it is suggested that the valve discs (107, 109) provide a stepped increase in flow cross-section in a respective flow path to or from said utilization elements (205a,b), wherein said stepped increase is dependent of the angle of rotation between the valve discs (107, 109). |
