<p>Non-return valve preventing reverse flow of gases, thereby preventing a gas mixture from reaching pipelines or cylinders Flame filter to quench the flame front of a flashback or a burn back Temperature activated cut-off to prevent further gas supply in case of fire (activated if the temperature rises to approximately 100° C). Pressure activated cut-off to prevent further gas supply after a flashback (activated by the pressure shock in front of the flashback).
