A horizontal and vertical shock responsive fluid valve assembly which are capable of automatically closing a fluid valve in response to earthquake forces or other shock forces of a predetermined magnitude. The assemblies are comprised of a respective horizontal and vertical shock and vibration force triggering mechanism working in a similar fashion. The mechanism has a respective cradle comprising a generally concave transverse surface that holds a movable ball and when it is energized by the forces can rotate 360 degrees in any direction and rolls out of the surface such that the ball ricochets off a housing cover covering the cradle and activates the mechanism only when the external forces reach a predetermined magnitude.
