The invention relates to a leveling valve (101) for discharging and supplying air from and to a plurality of utilization elements (205 a,b), in particular pneumatic suspension bellows, the leveling valve (101) comprising a valve arrangement (103) for directing air between a source (207) of pressurized air, an exhaust port (3) and said utilization elements (205 a,b), and a supply port (1) in fluid communication with the valve arrangement (103) and the source (207) of pressurized air. In particular, the invention suggests that a check valve (5) is mounted upstream of the valve arrangement (103), the check valve (5) being configured to allow fluid flow from the supply port (1) towards the valve arrangement (103) and to block fluid flow from the valve arrangement (103) through the supply port (1).
