Then for electric ball valves for a variety of ways to use, such as switching cut off or regulation and other control requirements, including explosion-proof or non-explosion-proof requirements, etc., different functions can be applied to different working conditions, that for their different wiring, it plays an important role, the following for the majority of users to the most common (AC220V) as an example, to do a simple description for reference, I hope to help you.

AC220V standard switch type electric ball valve wiring diagram	AC220V Integral switch type electric ball valve wiring diagram
AC220V regulated electric ball valve wiring diagram (4-20mA)	AC220V regulated electric ball valve wiring diagram (0-10V)

Note: The above wiring diagram is for reference only, the actual product circuit diagram shall prevail. In addition, each manufacturer's electric device are not the same, wiring are not the same, please do not take this as the standard to perform the operation, if a series of problems and related accidents, the company is not responsible for, please note!
