I have one set of remotes, pressure and return to the tank. Does the power beyond setup have a pressure relief valve built in? I would be concerned about having a saftey of somekind with valve in between the pump and the 3 pt lift. I can see what your talking about now. I need the 3pt to lift then be able to rotate the plow. bjr
Most valves have a pressure relief valve in them, and most are adjustable to suit your pump max psi.
I believe in your case it is around 2280psi. I set Loretta's relief valves on her 284 at 2250psi to be safe. The power beyond is usually an option, so you could get the same valve without power beyond if you are not planning on feeding another valve down the line. In your case, I would get it since you want to feed the 3pt valve after the new valve. That will avoid any functional problems with either valve in your system.
One thing I did is add a pressure relief valve right after the pump high pressure output.
On her tractor, she has a loader. If she ever disconnected the loader and ever forgets to plug the hyd lines back together so the fluid could continue to flow, the pressure relief valve would prevent her pump from blowing up. In your case, you would not need that. If you ran the high pressure line to a new valve with a pressure relief valve in it, that would work. I believe your 3pt valve has one built in it too, so you are good to go.
Another thing is she also had one "set" of rear remotes and a valve to control it.
However, it never worked very good. Perhaps it was not a true rear remote valve and needed that knob turned in order for it to work properly? Anyway, I replaced it with a 4 spool Prince SV valve and that set up works great. There is no need to turn that knob now ... the 3pt and new valve when each is activated... just like you want to do. You may not need a 4 spool and a one, two or 3 spool would be less expensive. But I would get at least a 2 spool valve so you have 2 sets to use for whatever you want. While you're at it, you may as well install a $15 pressure gauge to monitor the system.
Did you go to that link to check out the valve and installation?
Here is another thread starting on post #130 about the other valves on her tractor. That might be of interest also.
