If I understand this, you are using a third valve to select one of the set pressures? So the cylinder is connected to the common of the third valve? If that is the case, at first glance, I think it is legal and satisfies the pneumatics rules. I have been over ruled before so I can only suggest you ask the Q&A for the only valid answer.
I am only knowledgeable on the rules because it is what I am required to do as Chief Robot Inspector. All team members should read the rules.
