Abstract: A single one time use valve, based on a Shape Memory Alloy (hereinafter—SMA) actuating component, wherein the valve comprises a nipple component given to shearing and shoving from the instant of its being severed off, in a manner that enables passage of the gas or the liquid from the valve's inlet flow opening to the valve's outlet flow opening wherein the valve is a valve of the normally closed type, or enables stopping of said gas or liquid passage from the inlet flow opening to the outlet flow opening, wherein the valve is a valve of the normally open type, and wherein the valve is characterized by that the inlet flow opening and outlet flow opening are formed substantially on at least one plain, that extends in its direction wherein it is substantially orthogonal to the valve's house assembly lengthwise axis and wherein a physical demarcation exists all the time between the gas or liquid to the valve's SMA made actuating component.
