Question Coltri Sub Cylinder Valves

[Debesh Sanyal]

Lately, a few Coltri Sub Cylinder valves, without any provision of Burst Disc on one side, is doing the rounds. How safe would it be to try these valves out? And what could have made Coltri Sub release a valve without the safety feature of a burst disc?

AFAIK EU didn't demand the safety feature of a burst disc. So, don't keep your cylinders overfilled and store it away from direct sunlight.
