MF 1135 priority valve

Does anyone know anything about MF priority valves? I gave a little bit of history in my thread MF 1135 Hydraulics, but so far no one has given my any ideas of what to do. I believe I have a piece of crud stuck in an oriface in side the priority valve. I have soaked it in brake cleaner, carb cleaner, and tried blowing from both ends with up to 170 lbs of air, and nothing moves. Any other ideas of what to do, or is there supposed to be a way oil moves thru it. It is only slightly restricted in one line to the steering, and not at all to the line going back to the reservoir. The first pic is of the outside of the priority valve showing the ports. The next one shows inside the intake, observe the 2 fair size holes, one going to the return, the other to the steering. The small holes in back go to the steering, brakes, and one more thing, I'm not sure of. The last pic shows inside that port, at a needle or ball valve. Suggestions, other than a box of dynamite would be appreciated. I guess if you could tell me where to get the box it might be too. I'm thinking about just putting it back together and running it. Brakes and steering are overrated Guess I'm too new to send pics.

I've removed your photo restriction. You should be able to upload or post photos.

Thanks,

Yt, thanks for lifting my restriction. I hope these pics will help someone. I think they are in the same order as above. After soaking the valve in brake cleaner, and carb cleaner, and blowing both frontwards and backwards, maybe it will work. Trying to convince myself. I believe the pump puts out 2300lbs (over 2000 I know) and it's a straight shot from it to the valve. It might work.
