I'm looking for the same one, pm me if you have it. Turned out, this air conditioner expansion valve is pretty difficult to find, even though I checked every local store. I understand that the model is old, but it's less than 10 years old, so why is it so rare? At first, I even thought that my aircon needed extra cleaning. I ordered professional chemical cleaning from https://www.airconservicing.org/type-of-aircon-service/, but the problem didn't disappear (however, the aircon looks like a new one). Sure thing, the problem was in the damaged air conditioner expansion valve.
