3 way motorized valve function

1.SAFE AND RELIABLE- Made of durable brass, this valve is safe and reliable; The estimated life expectancy of 80,000 to 100,000 cycles means it is built to last
2.NPT THREADING- 3/4” quality brass thread, manufactured and measured according to National Pipe Thread standards; This electrical ball valve is full port, meaning the bore in the ball is a full 3/4”; This minimizes pressure loss through the valve; Perfect for home automation projects
3.9V-36V DC- Works effectively over entire voltage range; Will open or close valve in 3-5 seconds; No power expended once fully open or fully closed
4.STANDARD OUTLET PLUG- Simple outlet plug connection; The valve completely de-energizes after opening or closing
5.ALTERNATIVE TO SOLENOID VALVES- Automatically cuts off 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

Flow direction

Before order, please choose which flow direction you need, see below picture:

Wiring diagram

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: 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
Please Note A20 CR2 02 must need charge time >10 seconds for every time use

Valve Actuator gear

our A20 actuator gear is brass(biggest gear) + stainless steel



Our electronic components are basically imported, all choose the better quality of the accessories, such as switches, we use better quality Taiwan switch.

When you inquiry the valve, pls confirm the detail technical data :

1)valve size
2)material, brass or stainless steel?
3)working voltage
4)wiring diagram
5)thread BSP or NPT?
6)quantity?
7)cable length, 0.5m is OK for you?
8)flow direction?

How to use our A20 manual override

motorized valve from full close to full open(S-O), the manual override need 7 turns
