Hi I setup my tractor with a steering motor because that was the easiest at the time. Now I would like to upgrade my Genius (8770 supersteer) to a hydraulic valve. What are some suggestions for valves with model numbers. Much of the links that I find on this forum are back to the old discourse and are broken. Would also need guidance on pressure sensors etc. I see mention of HyrdaForce and DanFoss on here my boards have the Citron motor driver can I run the Danfoss on the cirtron?
Also some part numbers would be helpful to start getting some prices.
It can be pretty tricky to install additional valve on a complex system.
Most high end tractors like your Genesis have a variable displacement piston pump (closed centre load sensing) with priority for the steering system.
If you have 5 hoses on the orbitrol you should be ok just tee in left, right, tank and pressure and a shuttle valve for LS.
In this case for an Hydrafore valve you would only need this kind of body.
Probably no need for relief valve and pressure compensation on pressure line.
But this can only be confirmed by looking at the schematics.
It’s the port 1, you just connect in the orbitrol LS line with a shuttle valve.
If you go for Danfoss, you need PVG16 valve group with an external PVFC valve in the LS side. I would go for the PVEA-CI CAN-bus actuator in Danfoss setup, no need for analogue driver boards, needs of course bit of tinkering compared to a standard PVEA-S/H/A setup that’s supported out of the box by AOG.
If / when I build the next hydraulic system, I’ll put in directly the Danfoss EHi steering valve group, price difference is around 200 eur caompred to PVG and you get everything in one package, as added bonus also the steering cut-off valve.
Hi Pat I can’t believe how hard it is to find a valve! One guy I’m talking to wants a complete part number for the hydraforce. Do your have the full part number? I’m thinking SP08-D-6T-N-12-DL and 7025860 for the block based off the pic below. Does that look right?
In my case SP10 works good but I think SP08 would be fast enough for U-turn and would be a little smoother for ABlines.
But I have a 5T 115 hp tractor, maybe SP10 is great for bigger tractors like Genesis, In this case SP10-58C would be the best choice.
SPxx-58D: counter balance or double check valve works.
Ok I finally received my Hydra force valve SP08-58C-6T-N-12-EL. In an earlier post it was mentioned that I needed this and a shuttle valve is that correct? If so could someone give me a bit of a sketch schematic to get me started?
Edit: reading through this again. Is it just the 58D that requires and additional valve?
Ok as mentioned earlier I got the valve. Warm weather is here and I now need a diagram earlier I thought there was some on this forum but I can’t find any right now. Would someone have some advice for the below diagram?
-Do I also just Tee the P and T lines?
-And what about the case drain on the orbital?
-Also the where does the pressure sensor go for the steering cutout?
