I think it's possible to differentiate between a virtue and a value: a virtue requires a conscious and possibly moral choice, a value does not. That is why we use the phrase 'to make a virtue out of necessity'. Thus qualities like reliability, which inanimate objects and research data may possess, are not always virtues.
I considered linking 'value' to 'evaluation' — then a value is something you can evaluate, but a virtue is not. The thing is that 'value' need not imply 'quantity' nor lead to quantitative evaluation. This makes things difficult.
