On a trip in 2015 I bought a plastic card for the metro in Valencia, Spain.
It seems to be a Móbilis Card as shown here:

Are these still in use and will my card still be working on my trip next week?

They are still in use according to the EMT website
However the Spanish version is slightly more informative and suggests they expire after 5 years. That may just mean you lose any stored values and can recharge it or that may not even be possible.
