You've probably heard many times about racers forgetting to turn their air bottle on, and in turn losing a round. That's why Biondo decided to develop a product to prevent that occurrence from happening. Hence the CO2 Automatic Shutdown Valve was created. You can hook this up to your ignition switch, and never have to turn the bottle on or off again. This system mounts easily between your bottle and regulator, and the solenoid can withstand up to 3000 lbs. of pressure. 12v and 16v compatible.
