The dump looks similar to the one we use in Merlin, weve used it for about 2 1/2 years in hundreds of fights on FP and never had a problem. I did see after about 6 months that it was only rated to about 300psi, but has never failed me even after a fight when its been solid ice! saying that tho it could be a different model.

The only posistive thing i could see about the valve between burkert and ram is that it would stop a miss fire if you were to open the bottle too quickly. Although personally i would have put it just after bottle as the bottle valve looks abit small and fiddly.
