Wiring control diagram 1:
Input signal 4-20mA, 0-5V, 0-10V, 1-5V, 2-10V, output signal PWM:

1,RD(red wire) connect to DC9-24V+positive pole.
2,BK(black wire) connect to DC9 ~ 24V-negative pole, 4-20mA-/0-5V-/0-10V-/1-5V-/2-10V-negative pole.
3,GR(green wire) connect to analogy signal+ positive pole(4-20mA, 0-5V, 0-10V, 1-5V, 2-10V). 
4,YW(yellow wire) connect to ERROR output- negative pole. Wet contact NPN triode collector output. When there is an error causing the motor to work with excessive current, such as when debris blocks the valve and the ball cannot rotate, the contact is closed, when working normally, the contact open, It only can pull down the external signal. The load is 500mA
5,WT(white wire) connect to position feedback-negative.
Wet contact NPN triode collector output, OC output PWM signal, 100Hz, 5%-95%, indicating 0-90 degrees. The load is 500mA.

*PWM: Connect a pull-up resistor from WT to RD, usually use a 1k or 5.1k resistor, recommend using 1k for power supply below 15V, and 5.1k for power supply above 15V. Oscilloscope clamp connects to power's negative pole, and oscilloscope probe connects to PWM white wire.
*5%-95% represents duty cycle,  which is the ratio of VCC time to the cycle time.
*PMW signal is a position feedback signal, the error signal needs to be connected to a 10k resistor to power's positive pole. When blocking occurs, the error signal to the ground voltage will be lower, at this time, it is able to test signal with oscilloscope.


Wiring control diagram 2:
Input signal 4-20mA, 0-5V, 0-10V, 1-5V, 2-10V, output signal 4-20mA:

1. RD(red wire) connect to DC9-24V+ positive pole.
2. BK(black wire) connect to DC9-24V-negative pole.
3. GR(green wire) connect to position input /control current / control voltage+(4-20mA, 0-5V, 0-10V) positive pole.
4. WT(white wire) connect to common signal input and output signal's negative pole.
5. YW(yellow wire) connect to position feedback positive pole, output signal 4-20mA as the feedback signal.

* When output signal is 4-20mA, the maximum load resistance is the input power voltage (v-2) /0.02, e.g. if the power is 15V, then (15-2)/0.02=650Ω, it is recommended to use a 300Ω load resistor.


Wiring control diagram 3:
Wiring of input and output signal both 2-10V
1. RD(red wire) connect to DC9-24V positive pole
2. BK(black wire) connect to DC9-24V negative pole
3. GR(green wire) connect to position input /control current +/ control voltage 2-10V
4. WT(white wire) connect to common signal
5. YW(yellow wire) connect to position feedback positive,output 2-10V signal



Please confirm the below technical datas before inquiring:

1, valve size, materail, thread standard
2, Input control signal
3, actuator cable length


Advantages:
-This unique compact motorized valve is used for specific applications in air or geothermal heat pumps, drinking water systems, solar water heaters and other industrial equipment.

-This unique floating ball construction type ball valve requires very low torque and can be controlled with a small compact actuator.

-Automatically reduces power once fully open or fully closed; This reduces likelihood of overheating, making it a great alternative to solenoid valves for projects where a valve needs to be open for an extended period of time.
