[Dsg-mvt] [New Logentry] Follow-up Re: Premix Bottle Leak Detected

The relief valve has been replaced on the EEL setup, see attached picture.

The new valve is a Control Devices ST25 series (ST25-0W035), which is claimed to be bubble-tight to 10% of the set pressure (35 psi). No bubbles were observed during the leak check. Bench testing shows they start to relieve at the lower end of 30-35 psi.

We charged the line with Ar to ~20 psi then closed the manual valve after the bottle regulator to see if it maintains that pressure over the weekend.
