What did i do wrong with this exp' valve?
evening all
I changed an expansion valve and motor (BEV71) on a Daikin VRV today and as soon as I put pressure in the system it leaked from the motor and its casing fell off as if it had been dropped and broken !!
seems as if all the pressure is going straight into the motor assembly ????????????
I know its sketchy but hopefully someone can point me in the right direction.
its probably something simple that I cant see for looking .. stress job fuddling my head !!
any help appreciated
cheers

Did you overheat the valve body when you brazed it in?

Did you wet rag the valve body when brazing? Or overheat the body as Brian has said?
