Hydraulic Multipiers

Trace the hoses from the FEL valve (not the ones to the lift/curl cylinders) and they will connect to the front hydraulic block. It should be on the right side below and behind the engine.

When connecting an aux valve it should be in series with the FEL valve and placed after the FEL valve.

Your Operators/Owners manual should describe the front hydraulic block. My B series manual does.

Thanks MadReferee, I did look in my manual and what with you told me I understand now, or at least I think I do

Are you going to use a new manual hyd valve - a new lever somplace- and then electric buttons on that lever? Leaving your loader control & hoses alone as they are now.

Or are you going from the oil supplied to your loader, after your loader control lever, & use electric buttons on the loader joystick lever?

Either will work, butit will make a difference on ow you set this up....

I would like to go, oil suppplied ot loader after loader control lever and use electric buttons on loader jowstick lever

Moemoe,
Here are three choices to do what you want to do:

1. If you have an SCV now use a diverter. This is pluged into the existing outlet and splits it into multiple outlets. I have seen them as high as 8 splits.
2. There are valves made that will go in series with the FEL hydraulics that will add 2 more SCV's. The down fall to this application is you lose a function from the FEL when you are operating the extra SCV's. Some people do not mind this. On a 4 in 1 or a grapple you often need all of the loader functions as well as the grapple or 4 in 1.
3. Tap in to the power beyond circuit with a directional valve. You can add multiple valves to obtain the amount of outlets you require.
Each of the options can be ran from a newly installed handle on your loader stick.
You must be careful with the different types of valving. Some of the aftermarket valves will not work with single acting cylinders, ie. bat wing mower, planters, etc.

gates, if I tap into the power beyond circuit with a directional valve to use for the grapple functions, would I loose any of the other functions (curl,tilt, etc.)of the fel or would everything work? I think that is the way I would like to go. I believe the fel and top&tilt cylinders are not single acting cylinders so in that aspect I'd be ok? What is the difference of a directional valve and a scv or the diverter? I appreciate you guys for being patient with me. I'm new to this hydraulic thing and want to do it right. better safe than sorry. My dad used say the stupid one is the one afraid to ask the questions.

Moemoe,
Not a problem. I will try to make it as simplistic as possible.
You should not loose any other functions on the machine by tapping into the power beyond, if you use the correct directional valve and it is installed in the correct area.
The loader, I think you meant to say the grapple, and the top n tilt are double acting cylinders.
SCVs are the hydraulic connections on your tractor, they usually have a quick coupler on the end. It is the place that you plug in your hydraulic accessories.
A directional valve can be set up for contiuous flow between the pump and the tank and handle much higher flows with less pressure drop, ie. less heat. This type of valve is what you should use in the power beyond scenario. When the valve is activated the continuous flow is directed to the port that is selected.
The diverter valve plugs into your existing outlet (SCV) and acts as a multiplier. It can create multiple outlets from the one outlet. It diverts the flow from the original SCV to any of the outlets you select.
The power beyond scenario allows the function to be activated with the press of one button which can be located on your loader stick. This allows seemless operation of a 4 in 1 or grapple.
The diverter scenario requires that you activate the SCV that the diverter is plugged into and then select the outlet port you want the fluid to go to. This requires you to let go of the loader control or the steering wheel to activate the SCV lever, then select the outlet location on the diverter by pressing a button that can be mounted on the loader stick. As stated earlier some of the aftermarket kits are mounted on the front loader circuits and require one of the loader functions to be disabled while you are activating the 4 in 1 or grapple. Some people do not have a problem with it. Having operated multiple 4 in 1 equiped loaders for many years IMO being able to keep your hand on the loader stick and operate the 4 in 1 or grapple without losing the loader functions is the only way to fly!
I will again emphasize that valve selection is critical. Flow rates and pressure drops, creating heat, are important factors in valve specification. Please be carefull, especially if you use the power beyond circuit.

Ron, I believe at this point he only has the loader ports, no rear set.

I believe he does not want another hyd lever/ spool set, he would like to run all hyd from his loader joystick.

I believe the option he is looking at involves disconnecting one set of loader hoses, plugging in a stacked electric diverter/ multiplier, & having several electric buttons on his loader joystick. From this setup his normal loader funtion will work, until he pushes a button, then one of the loader options will momentarily stop working, and the flow of oil will be diverted to whatever button he has pushed. This would be the grapple, or the Top, or the Tilt. The grapple will be plumbed with hose to the front, the Top & Tilt hoses will be plumbed to the rear.

He would not be using the power beyond, nor the hyd block, to come from. He would be tapping off a working set of hoses.

This may be his cheapest route, but it will not be 'cheap'. /forums/images/graemlins/smile.gif

It will require some thought to remember the right buttons to push.

=====
In a perfect world, it would be better to put one diverter on the loader to run the grapple, with one push button.

Then add 2 ports (through power beyond port or the hyd block) that go to the rear, with seperate levers controlling each. Much easier to remember how to control what, and less fumbling with buttons.

But, this would add even more $$$ to the project. The diverter hooked into the loader bucket curl, with 3-4 buttons to divert the oil flow to other hyd ports will probably work out as well, for less money, for him.

Am I thinking somewhat clearly on this?

Rambler, you hit the nail on the head. That is exactly what I want to do, and like others money is a concern. gates, I,m sorry if I misled you to believe That I already had the rear remotes, as Rambler pointed out all I have right now is the fel.

To do what you want you need the V&M SV Directional setup with the multi-button control handle. It will do what you want with the least hassle although it will not be cheap. I would call V&M and ask their technical support people all your questions. They will be able to help you with your choice.
