My job does test so I had purchased some drug screen urine test cards for benzos just to see how long it would take before it got out of my system. I figured probably 72 hours, well it actually took 8 days for my tests to start reading a negative result.
Benzodiazepines like Valium can stay in the system a pretty long time. It depends on how much you take and for how long. Also your health, age, weight and metabolic rate play a part. How long a drug stays in your system depends mainly on it's elimination half life. For Valium (diazepam) the initial distribution phase is followed by a prolonged terminal elimination phase (half-life up to 48 hours). The terminal elimination half-life of the active metabolite N-desmethyldiazepam is, on average, 100 hours.
