A height control valve assembly having a housing (30) with an air supply port (76), first and second ports (72, 74), and an exhaust port. A valve (34) positioned in the housing (30) has a first surface in fluid communication with the air supply port (76) and a second surface. The valve (34) moves between first and second positions, in which the second surface sealingly engages a portion of the housing (30) surrounding the first and second ports (72, 74), respectively, to prevent fluid from flowing between the air supply port (76) and the first and second ports (72, 74), respectively. The valve (34) is moveable from either of the first and second positions to a fill position, in which the air supply port (76) is in fluid communication with one of the first and second ports (72, 74), and an exhaust position, in which one of the first and second ports (72, 74) is in fluid communication with the exhaust port. |
