Using the notion of cyclically pure injective modules, a characterization of rings which are locally valuation rings is established. As applications, new characterizations
of Prüfer domains and pure semisimple rings are provided. Namely, we show that a domain $R$ is
Prüfer if and only if two of the three classes of pure injective, cyclically pure injective and RD-injective modules are equal. Also, we prove that a commutative ring $R$ is pure semisimple if and only if every $R$-module is cyclically pure injective.
Keywords:
