The flow control arrangement has three operative positions including an initial extended set-up position, an intermediate compacted flow communication position and a final detachment position for separating the drug vial adapter and the liquid vial adapter. The liquid vial adapter and the drug vial adapter are engaged in the initial extended set-up position and the intermediate compacted flow communication position. The self-sealing access valve is closed in the initial extended set-up position and compressed open in the intermediate compacted flow communication position.
