A height control valve for a suspension leveling system having a valve assembly cartridge that is assembled prior to insertion into the valve body. The cartridge is threadedly received within the valve body to permit accurate setting of the valve center. In a second aspect, the height control valve includes a locking key which interlocks the drive bearing and valve body to discourage unauthorized tampering with the internal components of the valve. The locking key is resiliently secured beneath a seal that is inaccessible once the valve is assembled. In a third aspect, the height control valve includes a cap diaphragm extending between the cartridge plunger and the valve body to seal the cartridge bore and ensure that exhaust air is vented out of the valve.
