Good except for two points that I think could be explained better. First, you didn't make it clear that the gas flows THROUGH the sintered flame arrestor. Second, you didn't fully explain the difference between the check valve and the pressure sensitive valve. I'm guessing that one (the check valve) responds to differential pressure but the pressure sensitive valve responds to absolute pressure?
Dear Sean, Thank you for your feedback and your positive comments to our video. You are right, the gas flows through the sintered flame arrestor. The gas non-return valve allows the flow of gas in one direction only, i.e. in the intended flow direction. It shuts off immediately in the event of gas coming from the other side, i.e. from the outlet side of the arrestor. Thus, the reverse flow of oxygen or compressed air into the fuel gas line, or the reverse flow of fuel gas into the oxygen or compressed air line is prevented and dangerous gas mixtures air are avoided. The pressure-sensitive shut-off valve is activated in the event of a pressure wave. The valve is tripped if the upstream gas pressure is at least 1,1 bar higher than the pressure at the inlet side of the flashback arrestor. Such pressure shocks are usually caused by flashbacks. The 4 safety features of a flashback arrestor are explained in detail in the EN730 or the ISO5175. We will try to consider your suggestions for improvement with the next video version.
Do non resetable versions have any advantages other than price?
great job
HELO friends, does the item already have a distributor?

Wow , nice engineering...!
