you don't get it, do you?. There is no safe way to detect (or control) the motor that will guarantee that the valve is fully closed (or fully open).

The only thing you can detect by current is if the motor works hard, be that fighting an obstruction or the end of travel. The only thing you can get by powering the motor for a given time is that the motor will do a certain amount of work, whether that work is fighting an obstruction or pushing the end stop you will never know.

Now, if what you are suggesting here is to say "if the high current happen before xxx time, it is not at the end of travel" what will you do if the motor overcomes the obstruction and the high current peak lasted 5 seconds and then the valve went all the way. You have so many "fuzzies" that you will not get reliable results (see my viscosity example below).

Now, all this does have a value: if you put in high current detect and if you sense high current before the microswitch at the end stop closes, you can sound an alarm "get the finger out and close the manual valve, something is wrong". that would be a much appreciated feature.
