Abstract: The invention relates to a valve for a compartmentalized tube or tyre, including a number of ducts for passing and increased sealing. It therefore has one end for coupling to an inflation/deflation system; another end in contact with the rim; a flow channel between both, with opening by means of a cover solidly joined to a mobile rod. The valve has at least two cavities with connection means to the airtight compartments of the tube or tyre. One cavity is displaced solidly joined to the rod, allowing gas or liquid flow through the communication channel between the cavities when in the open position. The existence of friction surfaces are thereby eliminated, increasing the sealing, the maximum operating pressure and the useful life. Additionally, the number of items in contact with one another are reduced, allowing for a simpler manufacturing process by reducing the level of accuracy required for the components.
