The valve is present to control the flow of cool air from the air pump (AIR system). If the valve melted, you are getting exhaust gas backing up into the system somehow, and a blocked converter is one possibility, but there are many others. Your car has 3 Catalytic converters, if it is an EFI car. You are going to have to take this problem to a professional smog test station and have them diagnose it for you. If you just start replacing parts yourself, you could waste hundreds of dollars and still not find the problem.
