ABSTRACT A device for turning off a valve for a utility such as gas or water includes a spring loaded valve assembly (131) and a valve stem (137) held away from a valve seat (140) by a latch (133). When the latch (133) is tripped, the valve closes. In one embodiment, there are two such devices (131, 142). Cables (125, 126) are passed from a pull ring (110) accessible to the operator and pass through conduits (114, 118, 127 and 129) to the spring-loaded valves. In the event of an earthquake or other emergency, the pull ring is pulled and the utilities are shut off. In a second embodiment, an elongated handle (23) is pulled to trip the catch of spring-loaded valve. In another structure, a short cable between the valve assembly and a levered door to the valve casing is manually operable to trip the catch.
