Abstract

-24- msTmmT SHOT-OFF DEVICE FOR PIPE 5 A shut-off device (10) for pipe for use in a pipeline for operation in response to ingress of water, has a valve (100) for installation in a pipe of said pipeline. The valve (100) has a valve member (110) supported for movement between an open position when the valve (100) is 10 open to permit passage through the pipe and a closed position when the valve (100) is closed to shut off passage through the pipe. Included is a buoyant member (200) associated with the valve member (110) for moving the valve member (110) to the closed position 15 automatically in the presence of ingress water in the vicinity of the buoyant member (200) .
