Grant, it seems you dont use pneumatics. The pressure is the highest when the bottle warms up, and our rules allow only certified bottles, and I have only 1 bottle certified to 135 bar. All the others are 200 bar and above.
Also, open the bottle and the PRD has to vent any pressure over 1000 psi.
Even a low pressure valve or ram wont explode at this pressure, it just will trow out all the thin seals and vent gas as a sieve.

The only things we have seen explode with pneumatics are rams that trew the rod because the moving mass of the arm ripped it out, or the cast ali head couldnt resist the force.

And even certified hydraulic rams can suffer from this, as no ram is meant to move at the speeds we want. Festo gives as max speed for most it rams 4m/sec. Hydraulic seals ,depending on kind and brand do only 2m/sec.

Gravitys ram achived unloaded speeds over 10m/sec.
