2 Wire Reverse Polarity

2 Wire Reverse Polarity - When the ball valve is fully open or closed, the actuator automatically cuts off the power supply to prevent circuit overheating during prolonged operation. Control method uses Reverse Polarity (black-negative, red-positive for valve open; black-positive, red-negative for valve closed), with simple wiring

Product Information

OP01 Wiring - 2 Wires, Reverse Polarity

1.Connects red wire to positive pole, black wire to negative pole, the electric ball valve opens. 

2.Reverse polarity, the electric ball valve closes. 


※ Once in position, there will be no power consumption. 

※ In case of power loss, valve will remain in its current state. 

※ Voltage of power supply for option：5V DC/12V DC/9-35V DC 

※ A DPDT switch is suggested for a simple set up.

※ Valve status feedback available for custom.

FAQ:

1. What is the Waterproof Rating of this valve? +
The motor's housing is rated at IP67 for ingress protection. If permanently installed outdoors, it is recommended to place it under a shelter or in a protective box to prevent prolonged exposure to rain.
2. What is the difference between N.C. (Normally Closed) and N.O. (Normally Open) ? +
In a N.C. valve, it's closed without power and opens when energized. Conversely, in a N.O. valve, it's open without power and closes when energized, blocking fluid or gas flow.
3.What is the difference between Full Port and Standard Port? +
In a full port valve, the internal diameter of the valve is the same as the pipe it's connected to. In a standard port valve, the internal diameter of the valve is smaller than the pipe size.
4.Can this be used for Drinking Water? +
Only the stainless steel valve body is suitable for drinking water. Brass (contains lead) and UPVC valve bodies should not be used for drinking water.
5.For auto return valves, what is the minimum On-Time required for electrical storage to enable closing when power off? +
To ensure automatic reset functionality when the power is disconnected, it is essential to power the device for approximately one minute to charge the capacitor in 2-wire auto return motorized ball valves.
