Aspects of the present invention relate to an apparatus 100 for use in an air suspension exhaust system. The apparatus 100 comprises a valve 110 shaped at a first end to engage with a biasing member 130 and enclosing a first cavity 180 at least partially defined by the valve 110. The apparatus 100 further comprises a housing 120 configured to house the valve 110 and the biasing member 130. The housing 120 comprises an air inlet 140; an air outlet 160; and an exhaust channel 150 provided between the air inlet 140 and the air outlet 160. The valve 110 is movable between a closed position in which the valve 110 blocks passage of air through the exhaust channel 150 and an open position in which air can pass through the exhaust channel 150. The valve 110 comprises an aperture 115 provided through a wall of the valve 110 so as to allow air that flows through the exhaust channel 150 from the air inlet 140 to the air outlet 160 in dependence on a position of the valve 110 into the first cavity 180. An air suspension system including the apparatus 100, and a vehicle including such an air suspension system are also disclosed.
