A shock actuated shut-off valve for fluid flow lines is provided which includes a valve housing having a central chamber in communication with (a) a hollow inlet conduit, (b) a hollow outlet conduit and (c) a hollow, outwardly enclosed stowage arm in upward, substantially plumb communication with the central chamber. A valve element is disposed in the stowage arm in spaced relationship to the inner wall thereof and is releasably supported therein by a support member secured to the inner wall. Vibratory force effects displacement of the valve element from the support member and transition of the same into the central chamber where the valve element sealingly engages the chamber to interrupt the fluid flow passage from the inlet conduit to the outlet conduit.
