ABSTRACT:
The invention is a shut-off device for a gas or liquid conduit that closes the conduit upon receiving a signal from a leak detector. The shut off device is a spring biased full flow ball valve positioned in the fluid conduit that closes upon receiving a signal from the leak detector that a fluid leak has occurred. The detector may be a conductivity detector for liquids or a specific gas detector, and may be hard wired or remote signaling in operation. Multiple detectors may be used in the system. An audible alarm is also activated when a leak is detected.
