Thank you!
So I was doing some research on these poppet Schrader valves on the hi side.
There actually is a company called Schrader International, they have specifications and photos of this Schrader valve, it is not a ball, it is a half round poppet on a stem.
To confirm my suspicions, this valve is used for high flow of refrigerant charging on production line manufacturing, in this case automotive.
Even though you can, this port not for pressure testing. For one thing it's in the wrong location, it's on the compressor discharge, usually the high side service access is on the after side of the condenser which would be the line going to the orifice and evaporator.
Example, when I was charging the system in the very hot sun in my backyard the other day to get anywhere near evaporating pressures of 30-50 lbs, the discharge high pressure was hitting 300 plus. That would scare most novices.
