Thermatic Expansion Valves

Thermatic Expansion (TX) Valves

The TX valve is one of the most critical components of an air conditioning system.They are responsible for converting hot liquid refrigerant into a cold atomised vapour whilst regulating the amount of flow that enters the Evaporator.  From time to time the TX valve will fail, shutting down and starving the Compressor of vital oil or alternativly staying wide open and flooding the Evaporator with liquid therefore no cooling as a result. 

That is why manufacturers WILL NOT warrant a new compressor if it has failed due to non replacement of the TX Vave and Receiver Drier.
