John W. requested that I increase the air pressure applied to the top of GV7's piston to ~20 psi so that we could be assured that the "Soft-closed" GV7 gate was in full contact with its O-rings. If not in full contact, IP6 might be pumping hydrogen from the X-arm which would confuse the pressure comparison between the two BTs. -> As found, the piston close pressure was ~5 psi -> I increased this to 20 psi -> GV7's gate cammed fully closed a few minutes later
GV7 is now "Hard-closed"
