I need to run hydraulics to my backhoe valve from my loader valve. The inlet and outlet on the loader valve are 1 in. O.D. steel tubing. Can I run braided hose from the outlet on loader valve to inlet on bh valve and outlet of bh to TANK?

The hose will be a lot easier than the steel line, as well as cheaper. For sure go with rubber.

As to the power beyond, that can get tricky, & beyond me. But you really should be using a power beyond port, or you will have problems if you are hooking both the loader & the backhoe to the pump at the same time. Open center valves do not like their return line to be used for the next 'pressure in' port - unpredictable results can be had from either valve even if it's not being used. Each valve needs to have the return line unrestricted, or odd things will move when not expected or overheat when not planned....

If you are disconnecting your loader & plugging the bh into the loader ports, that will work fine - tho a hassle to go between the 2.

There web site any help to you? Would it be one of their current valves, or something much older? This one says something about series hookup, but I think that still would be through a power-beyond port?

The back hoe I have uses rubber sheild hose to go from the loader valve to the back hoe valve so I think you could also. I know its sure easier to do it that way then with hard pipe

You need to know whether or not the loader valve is "open center" or "closed center" and whether it is "Power Beyond" capable or not. It may be as simple as connecting lines in series, but my experience in the past is that you need to talk at length to your tractor manufacturer and a good hydraulics supplier with valve models and serial numbers before trying to connect anything. Worst that could happen is that you continually dump across a relief valve in the tractor, build up heat and have pump failure fairly quickly. Second would be creating leaks in the valve and nothing happening with the bh.

The loader valve is "open center" but there is no "power beyond" port on it. I have talked with many Ford dealers and hydraulic suppliers. About half the Ford dealers say that "in series" is fine for my application. My setup is a Ford 345C tractor/loader with a Bradco backhoe attachment. My loader valve is a Husco but I cant find any serial numbers for it. No one seems to give me any info on the valve either. The hydraulic people that I talked with tell me that i will ruin my loader valve doing this. I talked with a man from Topeka, Kansas at a Ford dealer and he works with industrial machines and he said that I will be fine with my tractor valve.

Assume for now you run them in series and the loader is first in line from the pump. For normal conditions where you use the loader OR use the backhoe all is fine. But in the real world, you will probably get stuck someday. Now when you push down with the loader AND lift and pull the back of the tractor with the backhoe at the same time, the pump has the pressure of the two added together. That is hard on or may destroy the hydraulic pump. One end of the loader cylinder has this same high pressure on it. The other end of the loader at the same time has the same pressure on it as is being used by the backhoe. Not good for things.

I understand that if the loader AND backhoe valve levers were moved at the same time, then there would be pressure applied throughout the entire system.

I thought that if the loader was lifting the front tires off the ground the pressure was within the cylinders and loader valve, not all the way back to the pump. What is so different about the power beyond port from the outlet port on my valve?

Tweeter.
The differance is that hooking valves in series without a power beyond will cause the return section of the first valve to be pressurized when the first valve is operated. Depending on the internal design of the valve, this can cuase problems. Pressure feedback to the first valve, and some times locking up the valve can occur. Some valves will work to some extent while others will only work in one direction.

It all depends on if the loader is set up for a factory backhoe. If it is it probably has power beyond. If not you need a power beyond adaptor. They usually aren't too expensive. Most machines with quick attach hoes need a power beyond adaptor. Dave

You can run steel or rubber hoses as long as the ID is the same. Dave
