In this paper we present the results of VLBI observations of six radio galaxies belonging to the 2-Jy sample. The selected objects are 3C17, PKS 0620-52, PKS 0625-35, PKS 1318-43, PKS 1333-33 and 3C317. The first is a high power radio galaxy and the remainder are all low power objects. Our observations were carried out with a set of different arrays and frequencies, and cover a range of resolutions from a few mas to a few tens of mas.
Parsec-scale images are presented and discussed in the light of unification for radio loud galaxies. Estimates for the intrinsic plasma speeds in these objects in the proximity of the parsec-scale core and their orientation to the line of sight are in agreement with the predictions from unified models and with their optical and X-ray properties.
We will use Ho = 50 km s-1Mpc-1, qo = 0 and throughout the paper.
