Did you order true his website? I thought he has a webshop now.
Thank you, what is the dispatch time?
I would like to order a valve for a case8230 combine harvester from your site. however I donāt know what to choose and what the different options mean. 30-60L? connection type? What is the mounting plate for?

Sorry i dont work for baraki so i have no clue.
Has anyone been successful at installing a closed center valve from Baraki on a 50 series JD soundguard tractor? I want to install them on a 4250 and a 4455 if that makes any difference. Iāve been searching on here and I only found one thread about adding hydraulic steering where they were having trouble with a feedback line of some sort. Is there something odd about these steering systems or are they just a normal closed center system?
Also, Iāve seen some people put the valve block in the engine compartment. Does the heat affect them over time or is there any reason not to? It would make for a much cleaner looking install if I install it above the engine near the original hydraulic block that the steering lines go into.

The 4xxx models feature a servo system controlled by a gear pump connected to the steering wheel. There may also be a typical orbitrol that controls the actuator. It is then a closed system without Ls. In the pressure line P, the pump maintains constant pressure, so the supply and drain are connected via tees. For this system I use a special valve with a 2-way compensator which helps in smooth control. We installed it on these tractors, it worked very well.
I will check the documentation to see what type of orbitrol is in case 8230 and I will give you an answer as to what will fit. A standard 30l valve fits the 2188, 2388 series, but Iām not sure if the 8 series has the same arrangement.
If you order in the store, my employee will ship the same or next day. Iāve had some work on the farm recently, so I couldnāt reply quickly.
In JD 8220 you probably have an orbitrol with a built-in priority valve that is powered by a gear pump. In 8230 I used an OC 30L valve, it works well during automatic steering, but during fast manual steering, check on the steering wheel that the shut-off valves have too little flow. I will soon redesign the OC valve to the 60L version and it should work fine. I will add items to the store.
Thank YOU much! 
When can i (we) expect it?
Add it to the store early next week.

Anyone happen to have a part number for the āoldā pressure sensor?
Based on posts it seems to be NC type but I donāt have more details.
(We have an installation and using that sensor would be more convenient that redoing the wiring as the harness was prepared in advanceā¦)
Found it on Telegram but writing it here anyone needs it:
The sensor is a SUCO 166 416 0 31 063 NC
Better use a pressure transducer, it is more reliable and easier to adjust. You only need to connect an additional 5V, you can branch it from the steering angle sensor.
Helping out a friend by transmitting his issue:
So thereās an installation that has the new 3 pin connector. The valve was installed 3 days ago and the tractor was in use so I think not likely thereās a lot of air in the system.
The pressure sensor is normally at 12% when in use, they set it 24% it is able to disengage reliably.
However during autosteer enabled it sometimes suddenly spikes up to 75% disables steering then wiggles there between 75-79% for a minute or so then drops down to 12%.
Any idea what should we check?
It is an LS valve on a New Holland and AIO V4 STD board.
We have magnum with trimble hydraulic valve that was always disengaging. Turned out the steering motor was leaking inside so replaced if and it works again. We watched the voltage on the disengage pressure sensor and we would see voltage spikes just like when you would turn the steering wheel but we hadnāt touched the steering at all.
Hi all,
I am planning an auto steer build on an International Harvester 826 and would like to do the steering hydraulically. i have a few questions regarding using this Baraki valve on this tractor. attached is a picture of my factory hydraulic system:
the āControl Valveā in the picture bolts down directly to the tractors body. the oil supply (pressure and return) go through the base of the control valve directly into the tractors body without being visible anywhere. In my picture, they are the lines going down out of the control valve. I know i need access to these two lines, so i could have a spacer plate made to bolt between the control valve and the tractor that would give my the two connections, or, could i eliminate this ācontrol valveā altogether and use the baraki valve instead? I understand the purpose of the ācontrol Valveā to be IHās way of allowing for manual steering without the tractor running, as well as power steering when the tractor is running. turning the steering wheel builds pressure in the control valve and opens up a valve that allows high pressure oil from tractors pump to flow to the steering wheel and from there to the steering cylinder at the front wheels. if the steering wheel stops turning then there is no pressurized oil allowed past the control valve.
Ok. will the baraki Valve allow manual steering with out the engine running? should i worry about not having steering with out the tractor running? If i remember right the baraki valve does allow for power steering without any of the electronics being connected.
hopefully all that made sense, the bottom line for me is, when i install a baraki valve on this tractor, how had i best install it. If i have to space up the control valve to access my pressure and return oil anyway, am i better to not use the control valve at all, or is there a reason that i need to keep it?
thanks to all of you for the help! if any other pictures or info is helpful i will try to supply it. thanks!
if this question should go somewhere else, go ahead and move it and i will try to categorize better next time. thanks again!
Oh, and I read that there is apparently a website that these baraki valves are being sold on. Could anyone point me to the web address? Maybe i will learn something on there as well.
Very interesting steering system.
If the flow divider divides the flow from the pump into 2 streams with a constant flow ratio, e.g. 50%/50%, my standard OC valve connected in series between the flow divider and the control valve will work. I think that all manual steering functions will be retained when the AS valve is not used.
Yes. I was thinking about what could be the reason. The pressure sensor in the Ls block is mounted on the Ls port which connects to the Ls orbitrol. The pressure on the sensor can only be increased from the orbitrol side.
Hey, I installed a OC valve on an T7040. It works very well, but today I had one problem:
I started the tractor with the AOG main switch off to drive out off the machine shed. After about 30 minutes I started the traktor again with AOG main switch off und i was not able to steer. The steering wheel wheee locked. After turned on main and actived autosteer. I deactived it and now I was able to turn the wheel.
What could be the problem? The main switch switches the power supply of the Kaupoi PCB and the cable to the activation coils of the valve.
