The valve with the ring isn't a check valve, it's the over pressure relief safety valve.
A check valve stops the air from going back to the head when the motor shuts off.
The over pressure relief safety valve keeps the tank from blowing up if the switch fails to shut off the motor at the set maximum pressure. The ring is so you can pull it to test the valve.
If it has an unloader valve that bleeds off the air between the head and the check valve.

Not putting miles on your car is like not having sex with your girlfriend, so she'll be more desirable to her next boyfriend.
