A multifunctional valve features a pumping function and a vacuuming function. The valve can be implemented in any closed container having a removable lid or a bag having a resealable zipper or any other similar sealable feature. The valve also features a tethered plug to additionally provide sealing. The valve incorporates a spacer or washer when used in thin walls to provide support. When the valve is used with a bag, the spacer or washer incorporates footing so that the valve does not collapse on its own when the valve is used in conjunction with a vacuum pump or a gas pump.
