I just ran into an odd glitch, which I reported but did not get a confirmation.
I needed to go to the Psi Valorum Secotr Block so I went to the Regulus Sector Block to get there. But when I reached the boarder it asked me if I wanted to Warp to the Alpha Centari Sector Block.
So it seems that the only way to get to Psi Valorum is to go up to Alpha Centari and over to its boarder with Psi Valorum.
