A bi-fold valve door and method for controlling aircraft cabin pressure are provided. The bi-fold valve (118) door includes an aft door section (224) and a forward door section (226), and only the forward door section (226) is selectively rotated about one rotational axis (227) to a position between a closed position and a full-open position, while the aft door section (224) is maintained in its closed position. The forward door section (226) is selectively rotated about the rotational axis (227) to a full-open position to engage the aft door section (224), while the aft door section (224) is maintained in its closed position. When the forward door section (226) is in the full-open position, the aft door section (224) and the forward door section (226) are simultaneously rotated about another rotational axis (225).
