Using supersymmetric localization, we consider four-dimensional$\mathcal{N}=2$ superconformal quiver gauge theories obtained from$\mathbb{Z}_n$ orbifolds of $\mathcal{N}=4$ Super Yang-Mills theory in thelarge $N$ limit at weak coupling. In particular, we show that: 1) The partitionfunction for arbitrary couplings can be constructed in terms of universalbuilding blocks. 2) It can be computed in perturbation series, which convergesuniformly for $|\lambda_I|<\pi^2$, where $\lambda_I$ are the 't Hooft couplingof the gauge groups. 3) The perturbation series for two-point functions can beexplicitly computed to arbitrary orders. There is no universal effectivecoupling by which one can express them in terms of correlators of the$\mathcal{N}=4$ theory. 4) One can define twisted and untwisted sectoroperators. At the perturbative orbifold point, when all the couplings are thesame, the correlators of untwisted sector operators coincide with those of$\mathcal{N}=4$ Super Yang-Mills theory. In the twisted sector, we findremarkable cancellations of a certain number of planar loops, determined by theconformal dimension of the operator.
