No, these worth shouldn't be used interchangeably. They are similar and can be used in similar situations, but the words don't mean the same thing. "Valuable" has more to do with monetary worth, while "crucial" means extremely important or necessary. Ex: This artifact is valuable to our research. Ex: This part is crucial to the machine.
