Re: What is this?
It's a "normally closed" solenoid valve. The valve opens and allows flow to the apartment's air-handler when called for by the thermostat.

No expert on this, but you are probably right about the height and the "weight" of the liquid refrigerant being a factor although it doesn't appear to be a "pressure reduction" valve. I suspect it could screw the system up if the evaporator was left "open" when the whole system wasn't running.
