PURPOSE: A leveling valve is provided to save cost for controlling left and right air springs with one leveling valve at the same time and to decrease maintenance costs for minimizing economic burdens for users. CONSTITUTION: A secondary main body has a hinge portion(44) supporting a hinge shaft(36) of a valve plate(16) penetrating a shaft center part in a circular space part(42). On both sides of the circular space part, air feed ports(46,48) for supplying air to air springs are provided. Primary and secondary main bodies(12,14) and the valve plate are assembled with a fixing bolt. In addition, at the end of the hinge shaft, a lever(18) is fixed and the end of the lever is hinged to a vehicle body. When rotating the lever downwardly, the valve plate rotates clockwise to communicate with an outlet port(26) with a lower elongated hole(40). The air supplied toward the circular space part and the air springs is discharged through the outlet port. Thereby, with one leveling valve, the air springs at left and right wheels are controlled.
