Is there a way to bench test a RANCO Type H16 heater control valve for both thermocouple operation and seal leakage while it's removed from car?

I rebuilt my valve (with new NAPA seal). Would like to test before reinstalling.

Has anyone used a heat gun (hair dryer type) to test thermocouple and/or low pressure (<= 20 PSI) air to test seal?
