motor operated valve wiring diagram
motor operated valve wiring diagram can be a variety of, can be 2 lines, 3 lines, 4 lines, can also be connected with a feedback signal line, 2 lines can also be with ground wire.
Wiring diversification, according to the customer equipment voltage is different, line number is different, provide different wiring mode. Meet different needs.
CR2 01 Wiring Diagram ( 2 wires control )

·RD connect with positive, the BK connect with negative, the valve closed, the actuator automatically power off after in place , the valve remains fully closed position .
·BK connect with positive, the RD connect with negative, the valve open, the actuator automatically power off after in place, the valve remains fully open position .
﹡Suitable Working Voltage: DC5V/DC12V/DC24V
﹡Exceeding the working voltage is forbidden
CR2 02 Wiring Diagram ( 2 wires control – Spring return in case of the power is failure)

·When SW is closed , the valve open. the actuator automatically power off after in place
·When SW is open, the valve closed, the actuator automatically power off after in place
﹡Suitable Working Voltage: AC/DC9-24V,AC/DC110V-230V,AC/DC9-35V(with manual override).
﹡Exceeding the working voltage is forbidden
CR3 01 Wiring Diagram (3 wires control )

·RD & GR connect with positive, BK connect with negative
·When OPEN( RD) & SW connected , the valve open, the actuator automatically power off after in place , valve remains fully open position
·When CLOSE(GR) & SW connected, the valve closed, the actuator automatically power off after in place, valve remains fully closed position.
﹡Suitable Working Voltage: DC5V/DC12V/DC24V/AC/DC9-35V
﹡Exceeding the working voltage is forbidden
CR3 02 Wiring Diagram (3 wires control )

·RD connect with positive, the BK & GR connect with negative
·SW CLOSED, the valve OPEN, the actuator automatically power off after in place.
·SW OPEN, the valve CLOSED, the actuator automatically power off after in place.
﹡Suitable Working Voltage: DC9-35V
﹡Exceeding the working voltage is forbidden
CR3 03 Wiring Diagram (3 wires control)

·RD& GR connect with positive, the BK connect with negative
·SW CLOSED, the valve OPEN, the actuator automatically power off after in place
·SW OPEN, the valve CLOSED, the actuator automatically power off after in place.
﹡Suitable Working Voltage: AC/DC9-35V/AC110-230V
﹡Exceeding the working voltage is forbidden
Above wiring diagrams are all low working voltage, will be more safer to use.
but it usually don't suit for wall power supply (AC110-230v), it usually suit for equipment which only can offer DC24v power, Or use frequency conversion voltage to change voltage to AC110-240v.
