ABSTRACT:
This invention is a valve for isolating a fluid such as petroleum, oil or gas, in a fluid system, in the event of fire breaking out. A fusible cap containing a valve element collapses at a lower temperature than the material in the rest of the system, allowing the valve element to seal the system under pressure of a spring.
