Not often I ask a hydraulic question...lol. But I am on a quest to find a valve that my not exist for a specific application.
Wanting to add a remote set to a tractor that already has a backhoe installed.
Like most backhoe aux kits.....there is only two hoses. One coming from the PB of the loader, and one going on to feed the 3PH. They get away without running a PB setup on a backhoe because you cant use the 3PH with the backhoe on....which is why most manuals state to leave the lever LOWERED to not blow the backhoe valve.
Anyway....wanting to minimize cost for the person who wants this done....my Idea was as follows:
1. Use the existing line coming from the PB of the loader valve to supply the P port of this new valve
2. Use the PB outlet of this new valve to supply the 3PH on the tractor.
(those two hoses are already present)
3. Add a third hose to to Tee into a return line
4. Two new hoses from the work ports of the valve to the existing backhoe couplers.
This is to add a toplink cylinder to the tractor for a box blade. The backhoe couplings are not the typical AG couplers and they are different sizes so it can only hook up the correct way. This is no issue because I will get the right ends for the toplink cylinder.
Ideally I'd like to find a single spool valve....PB capable...10-20gpm range...and have a detent in ONE DIRECTION ONLY.
Everything I am coming up with either detents BOTH directions, or has pressure activated kickout like a logsplitter valve.
The reason I only want it to detent ONE direction is for when the backhoe is hooked up...it will just run off these "remotes". Dont like the idea of a bungee cord or potential to detent BOTH directions because the idiots that work for this guy would likely try and run it backwards and feed the backhoes T port instead of the P port.
Anyone have any leads on such a valve or have been down this road before?
