|3/4/5 Port Solenoid Valves

What are the polarities when electrically connecting DC type VT307/VT315/VT317/VT325 series valves?

If the color of the valve lead wire is red and black, red is positive (+) and black is negative (-). For DIN terminals and other terminals without lead wires, connect positive (+) to No. 1 and negative (-) to No. 2. If the lead wire is gray, it does not have polarity.
