In the last image you have PIN3 as signal ground. In the PDF sheet, page 7, PIN4 is marked for 5V. If the PLC analog was connected as you state above, then you have to swap PIN3 and PIN4. I further bet that PIN2 and PIN3 is internally connected --> you measured earlier 0V where an analog value should have been.

Or was it connected as you wrote with [+] on PIN3? What does [+] of the analog measure when the valve is connected?
