Abstract
A bidirectional solenoid operated valve for controlling the flow of a compressed gas to and from a pressurized vessel is provided which automatically blocks the flow of gas out of a cylinder to a gas line in the event of an electrical failure or crash and which will not fail catastrophically in the event of a crash. The bidirectional valve includes a manual lockdown feature, an integral electrical pass through assembly, and a thermally activatable pressure relief device.
