From pictures I searched on internet I see it has ordinary orbitol plus added stuff on top of ports. From that baraki post I searched “orbitol priority valve” and found danfoss document. From picture it seems to be same thing. Does your orbitol have same thing? Danfoss doc has diagram how it works. I don’t have LS systems so I’m not very familiar with them but this may lead to some idea.
From my understanding
LS static - no oil flow, pressure working principle
LS dynamic - requires dynamic oil flow ~1L/min
LS high dynamic - requires dynamic oil flow several litres per minute
Some valves require pressure to shift valves, other need oil flow to keep valves in desired position.
It works after swapping the LsT and LSO wires, now it is connected the other way around than in the diagram. And now I have a question, what about the pressure sensor, will it work correctly?
The sensor shows pressure but it does not increase when the steering wheel is turned. I am thinking of unscrewing the sensor from the block and screwing it into the appropriate place using a T connector
Hello,
I received a Baraki OC valve and it looks a bit different compared to the other pictures and diagrams (the coil layout is slightly different). I’d like to know how to wire it electrically – where should I connect plus and minus, do I need to add a diode in between, and if so, exactly where? I’m using an All-in-One Board 4.1.
Red arrows are the connectors for the directionnal valve, where you connect the PWM outputs of the AIO board (left and right, pins 5 and 6) : no diode on those connections.
Blue arrows are connectors for the 2 bypass valves, both to connect to the same ouput of the AIO board (lock, pin 7). You may put a freewheel diode, cathode on pin 7 and anode on ground.
If you confirm by testing with an ohmmeter that all the 4 coils are isolated from the main body of the valve, there is no plus or minus on them. you can wire in either way.
About hydraulic connections, is your valve an 30 l version or a 60 l version ?
I bought a 30 l model in 2025 january and it comes with the well known schematic for hydraulic connections : hydraulic valve OC.pdf (294,5 Ko)
Then I bought a 60 l model I received a few days ago, without any more information, BUT it’s not the same connections : T and P don’t move, but holes for hydraulic cylinder are crossed !!!
Baraki valves were only 30 l OC and 60 l LS.
But a new version 60 l OC appeared recently.
If you connect the 60 l OC as you connected the 30 l OC, you “just” have the driving wheel turning in the opposite side of your wheels !!
hello, i have New Holland TS100A and on orbitrol i have P and T hose bigger than R and L. On my baraki valve i have all connector for hose same size, do i need bigger one for P and T or its good small one?
Can someone help me? My Fendt Farmer has a standard gear pump, while the orbitrol has 5 lines. As far as I know, there’s some sort of priority valve on the orbitrol. Which hydraulic block does it need?
I have a self-propelled sprayer with no load-sensing system, BUT the orbitrol has 5 lines. Orbitrol is the addition of a Danfoss OSPC-LS and a priority valve OLSA.
In my case “Excess flow” goes to the valves which move the sprayer arms.
Be careful with Fendt farmer, because it seems to me that “Excess flow” is added to the main pump flow on theses tractors.
