Hello!
After i have completed 3 systems usink Keya motors i decidet to go for a Naraki valve for a 2012 Claas Arion 640 with Load Sensing hydrulics.
I have recieved the valve but to be honest i could not make the solenoids work. I am not sure how to power the solenoids and how the pressure sensor is working. It is my first time using Cytron (for Keya inused can) and on the board i have a conector where it saus 12 v to Cytron. Also i have no idea how to connect those 4 solenoids from the valve to the board. Any help would be greatly appreciated.
Ok, so to power your lock valves, get a 12v 4 pin NO automotive relay.
From the AIO PCB Ampseal plug, wire pin 7 to relay pin 86.
Pin 85 of relay to ground
Pin 30 of relay to Battery 12v+
Pin 87 to Baraki lock valve solenoids. The polarity doesn’t matter so put this to one of the pins on the lock valves the other pin on the lock valves connects to ground.
So you’ve plumbed this in how I did on my YouTube video, so you don’t need to use the pressure sensor, there is some firmware @bricbric and @Daniel developed that disengages the steering by detecting the error from the wheel angle sensor. It works really well.
I will post a link to it.

The proportional steering solenoids that do the steering, connect one to pin 5 on the AIO Ampseal plug and the other to pin 6.
Now it depends on how your PCB is configured, but power for the Cytron is either input to the PCB on pin 18 of the AIO PCB or it shares the 12v from pin 22. Put a picture up and can see how the PCB is setup or not.
The other pin from the proportional valves is just connected to ground.
It doesn’t matter which solenoid you connect to pin 5 or 6 you can invert the direction in the steer settings.
Hope this makes some sense.
Edit: I read your post again you have a connector from 12v to Cytron so Cytron will get power from the 12v+ into the PCB on pin 22.
To be honest with you, your videos are the main reason i have switched to hydraulic steering rather than using a keya motor. It will be nice to have the posibility to disengage the steering when the steering wheel is grabbed. This weekend i will have some spare time and i will wire the solenoids as you said. Inhave 4 solenoids on the valve, can you point the role of every one of them? I don’t want to mess up the wiring again?
