A storage system for storing and preserving food items or the like includes a sealable storage bag having attached to it a one-way valve element that communicates with the interior volume of the storage bag. The system also includes an evacuation device that can be positioned over the one-way valve element to evacuate air entrapped in the interior volume via the valve element. To avoid possible damage to the storage bag, the valve element, or the stored food items, the evacuation device is configured to have a maximum evacuation pressure of 6 pounds per square inch absolute or greater. In an embodiment, to control the maximum evacuation pressure of the evacuation device, the evacuation device can include a pressure control feature which in further embodiments may be pressure activated or user selectable.
