Abstract
A discharge valve adapted to be affixed to a container housing pressurized fire extinguishing materials. The discharge valve is opened by activating an explosive squib to provide a shock wave which destroys a diaphragm sealing the contents of the fire extinguishing fluid within the container or housing therefor. There are two explosive squibs, one of which may be electrically operated and the other of which may be manually operated.
