PURPOSE: A valve unit is provided to offer improved pneumatic components for the pneumatic circuit of a lift axle applied to an automobile having an axle suspended with a metal suspension spring. CONSTITUTION: A valve unit(2) comprises a housing(11). The housing comprises a supply port(7), a lift bellows port(9), a suspension bellows port(10), a lift bellows valve(13), a suspension bellows valve(14), one or more load dependence control valves(12). The supply port is installed on a supply line connected to a compressed air source. The lift bellows port is installed for the lift bellows(4) of an axle. The suspension bellows port is installed for the suspension bellows of a lift axle(3). The lift bellows valve controls the pressure of the lift bellows port. The suspension bellows valve controls the pressure of the suspension bellows port. The load dependence control valve controls the lift bellows valve or suspension bellows valve using pneumatic pressure.
