[Kyle, Chandra]

We leak checked the gate of this valve after suspecting a leak. Kyle cycled it five times on leak detector and four out of the five times it leaked (e-6 mbar-L/s range leak). Then we sprayed the gate with IPA to clean it and re-tested with three cycles. No more leaks! It could be that particulate fell on the gate gasket during rough down when it was installed on OMC NEG housing. 

We have since received six more of this valve model and decided to leak check all at once right out of packaging. All six are leak tight to a level of 5e-8 mbar-L/s background. I cycled each valve once while on leak detector.
