How to progragrammatically get NodeType translated value in D8?
You need to set the config override language to the desired language:

  $language = $language_manager-&gt;getLanguage('es');
  $original_language = $language_manager-&gt;getConfigOverrideLanguage();
  $language_manager-&gt;setConfigOverrideLanguage($language);

  // Load the node type here.       

  $language_manager-&gt;setConfigOverrideLanguage($original_language);
