The double phase transition of hadronic matter, H, first, to the gas of deconfined constituent quarks (for brevity called \it valons), Q, and then, secondly, the phase transition from Q to quark-gluon plasma, QGP, is considered within bag model ideology. In distinction from previous double phase transition investigations, it is not supposed that at zero chemical potential (~μ=0~) transition temperatures Td (for H~↔~Q) and Tch (for Q~↔~ QGP, chiral restoration) coincide. Then for plausible range of chosen bag constants, BQ for Q and Bq for QGP the phase transition H~ ↔~ QGP can proceed \it only via the Q phase (at least at not too much μ). For small μ the gap, Tch~-~Td, is quite essential, up to ≈~50 MeV. The physical meaning of the H~ ↔~ Q transition temperature, Td, coincide with that of the Hagedorn temperature, TH.
