Alan, I gave this response to Simon the other day:

A burst disc is a pressure relief device and as long as it is certified to rupture at 1000 psi then it would be acceptable from a safety perspective. I would not recommend it for the 1000psi limit as this pressure can be and has been achieved in outdoor summer events due to ambient temperature and direct sunlight. Once the disc ruptures, thats it, it does not re-seal afterwards.

Hope that helps

Alan,

Mutes relief valve was popping frequently at Eds event in the middle of summer.

Best stick to the refief valve as it will reset when the pressure/temperature drops off. I would have hated to see 4.4Kg of CO2 spew out from a ruptured burst disk... mind you it would have cooled things down a little cos it was a scorcher

i know once it blows then all your gas has gone, i was just looking at alternatives. Eds event (and rogers) were the only times i have known for the valves popping, but precautions could be taken to keep the bottles cool etc.

Again it all comes down to money, within the next few months we would need 3, thats £150, i could buy a new pair of hawkers instead, and as you know, we need all the batteries we can get at the mo!

I got some prices on burst discs. If you want the detail send me an e and I will forward. But Pauls relief valves still work out the cheapest option.
