A safety valve, also known as a pop-safety valve or pop-off valve is a specialty valve installed on a chamber to prevent over-pressurization. They are available in a wide range of pressure ratings, from pressures lower than you'd want to use in a spudgun to pressures higher than a PVC chamber will hold.
These are most commonly installed when you are using a pressure regulator, so that if it malfunctions it won't fill your chamber to the point where it fails, although no such event has been recorded.
Sometimes if you strike up a conversation with the plumbing guy at Home Depot/Lowes about building a combustion cannon, many times they will attempt to sell you a safety valve, even if the cannon you wish to build is a lowly hairspray inline. Remember, the plumbing guy usually doesn't know anything about potato guns. Don't trust them.
