Abstract
A one-shot, three-way valve having an internal tube forming a zero-leakage fluid path prior to actuation of the valve and having a ram moveable to an actuated position where the tube is cut in two. The ram has a passageway mating in the actuated position with one portion of the cut tube to establish another fluid path. The ram is configured so that, in its actuated position, the other tube portion is pinched by the ram to both close off this other portion and wedge the ram in the actuated position. The valve is adapted for actuation by a pyrotechnic squib and for reuse by convenient replacement of the tube.
