A shut-off valve for connecting between a water supply valve and a tank inlet port of a toilet tank includes a housing having an inlet port, an outlet port, a valve mechanism, a trip mechanism, and a trip circuit electrically connected with the trip mechanism. The valve mechanism includes a valve housing rotationally confining a first ceramic disk and a ceramic second disk, each disk having at least one aperture therethrough that, when mutually aligned, allow for fluid communication between the inlet and outlet ports. The trip mechanism includes a rotational spring that urges rotation of an axial shaft fixed coaxially with the second disk. A trip latch is adapted to prevent rotation of the axial shaft and second disk except when withdrawn from the axial shaft by a solenoid electrically connected to the trip circuit that is electrically connected with a toilet tank overflow sensor, a toilet bowl overflow sensor, or the like. Upon detection of a fault condition, the trip circuit trips the trip mechanism to prevent water from flowing into the toilet tank until the fault can be corrected, thereby conserving water and often preventing water damage.
