Wiring diagram

CR3 01 Wiring Diagram (3 wires control )
motorized valve wire control CR301
·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

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 or PVC?
3)working voltage
4)wiring diagram
5)thread BSP or NPT?
6)quantity?
7)cable length, 0.5m is OK for you?
