What is different between a flash back arrestor and a check valve?









A check valve allows flow in one direction only. This prevents oxygen reaching acetylene cylinder and acetylene reaching oxygen cylinder in the event of blockage in the torch or line or pressure variations.


But a flash back arrestor prevents reverse flow; stop the flow of flame from reaching the cylinder in the event of a flash back or the temperature exceeds a limit (220 degrees f.)
