Hi guys, I have trouble connecting my proportional valve to Arduino. the valve that I'm using has 5 wires, and I have no idea what kind of driver I need for this valve.
The valve operates with 12-24 and takes 0-10 volt signal to proportionally open and close.
I can open and close it manually by connecting the red to 12v and black to the ground and another 5 volts to green to open it halfway.
Please help
Please post a link to the data sheet or product page for the valve.
The manufacturer probably sells an interface/driver, or you can build one with discrete components, provided you know the valve input characteristics.
At the very least you will need a 12-24V power supply for the value and a 0-10V DAC module for the Arduino.
Hi, @sb27252
Welcome to the forum.
I believe this is your valve.
Can you please tell us your electronics, programming, arduino, hardware experience?
Thanks.. Tom... 
Your valve requires a signal in the range of 0 to ten volts. This voltage range will correspond to 0 to 100 percent open. That is why when you put 5 volts on the green wire it opened half way.
In order to control it with an Arduino you will need a DAC, a digital to analog converter. Most DAC’s will output a signal of 0 to 5 volts. I have seen some that will output 0 - 10. Maxim and Analog Devices are two manufacturers of these devices also Adafruit sell premade modules at fairly reasonable prices.
I find it interesting that the diagram on the box has different colors than the valve.
You will have to build your own driver, not to difficult.
You will need a few resistors, capacitors and one small IC.
