OAT 8*. head pressure control making a loud vibrating noise. Is this a sign of internal damage to the valve or diaphram or is it common at this low of ambients
I have no experience with that particular valve, but two of my supervisors have told me of instances where a ridiculously loud noise was found to be coming from a headmaster.
I would say yes. Have seen it once on a Hoshizaki IM. Replaced valve, noise is gone.

Liberalism-Ideas so good they mandate them
i've heard noise come from them on start up or pump down, what is the discharge and liquid pressures at?
Just shut down ckt 1, to dang cold out with windchill at -17* f. Will return at end of week to investigate. Customer happy and occupants in office below condenser happy with noise gone .
