Kelly,
The valve pictured is from the RX7.
The connections have been changed from the original configuration and soldered
to the core. This valve works to adjust the flow through the core but
wouldn’t be a reliable cutoff for safety purposes. Ball valves on
the engine side of the firewall for both the supply and return would probably be
a better arrangement. Either valve could be used for making adjustments, but
the supply valve would probably be preferred.
I have two small muffin fans in the glareshield
which blow air from under the glareshield onto the windshield. There is
no heated air supply from the heater core to these fans. So far, that
arrangement has worked fine. The humidity here is usually quite low,
however.
