While facing directly in-front of the TXV, to increase Super-heat you have to restrict the path way at the TXV, meaning it will need to turn it CLOCKWISE or (to the RIGHT if you are in front of txv) to close. To decrease Super-heat  you have to open the path way at the TXV, meaning it will need to turn it COUNTERCLOCKWISE or (to the LEFT if you are in front of txv) to open.
