[ What is claimed is:] [1.] Apparatus for regulating the flow of fluid through a supply line, the supply line having a valve for closing the supply line, said system comprising:a closure device for operating the valve to close the supply line in response to an electronic closure signal, said closure

[ What is claimed is:] [1.] Apparatus for regulating the flow of fluid through a supply line, the supply line having a valve for closing the supply line, said system comprising:a closure device for operating the valve to close the supply line in response to an electronic closure signal, said closure device comprising:ignitable powder means for applying a torque or force;gear means operatively connected to said ignitable powder means for amplifying the torque or force applied by said ignitable powder means to provide an amplified torque or force for operating the valve to close the supply line, said gear means having an open state for opening the valve and a closed state for closing the valve;attachment means operatively attaching said gear means to the valve;gear setting means for setting said gear means to the open state;releasable latching means for releasably holding said gear means in the open state; andtrigger means for igniting said powder means in response to the electronic closure signal, for releasing said latching means, to cause said gear means to close the valve.
