Abstract of the Disclosure . A fluid shut-off device is provided which comprises a non-magnetic casing having a fluid passage therein, a metallic valve body movably disposed in the casing to close the passage at one operative position, and a magnetic member slidably disposed outside the casing and magnet- ically attracting the valve body. The magnetic member takes an inoperative position against a spring force and is locked at this position. The lock is released by a bimetallic strap deformable by supply of an electric current. When the lock is released, the magnetic member is moved by the action of the spring force, so that the valve body magnetically attracted by the magnetic member is also moved to the operative position to shut off the flow of fluid material through the passage.
