Klingon Family Values

I can't understand how the english translation results from this klingon sentence.

It's because the Klingon tranlsation resulted from the English phrase ;-)

> All I get is "something consequential/important of klingon family".

That's correct. Aren't "values" something important?

Values are only a subset of important things. I wouldn't call a textbook QeD paQDI'norgh if it were a biology textbook.
