Is the overfill valve the same valve that shuts off flow if there is a broken line downstream that would allow uncontrolled release?
No the connector (QCC-1/ACME) has the excess flow feature.
Also, built-in thermal protection on the QCC connector melts allowing the nipple to disengage from the tank connection and stop the flow of propane.

The OPD (overfill protective device) has one function.....to prevent overfilling, when tank is in proper position to be refilled. It has no function when cylinder is in service.
