I'm slowly getting the picture, I think, there is still confusion as to which tank port sees what pressure. From what you're saying, the new valve's tank port would be subjected to the full pressure and it's not rated for that. The one that must be rated for the high pressure would then be the one on the backhoe. It's here that I think is confusing me, the backhoe has only one port or outlet used since there's only two lines to/from it. In your case, you don't have a backhoe, but you have the added valves and it's their tank port that can handle the pressure?The flow goes through all the valves in series. Pump -> loader -> 3pt. On each valve the flow goes out the tank port or PB port if the valve has PB, and on to the next valve. Unless the valve is actuated, then flow goes out the work ports. When you operate the 3pt, the pressure to run that comes from the pump, through the loader valve.
Now add an additional valve: Pump -> loader -> new valve -> 3pt. The pressure to lift the 3pt goes through the new valve. If you plumb it without using PB the tank port will see that pressure, which maxes out at about 2500 psi.
There are valves with tank ports that can handle full pressure. The dealer installed additional remote on my 3725 is one. But they are not that common.
BTW the last time I heard the factory remote kit was a lot less than other manufacturer's remote kits. With all the stuff you'll need to buy to DIY, easily another $150, plus fabbing brackets, it might make sense to price the factory kit. It does integrate nicely in the cabin.
What I would need to do then is to find a way to connect the tank port to the tank? I just did a request for the kit, might be a viable option
