***SOLVED***What valve do I need and where to buy one?

***SOLVED***
I posted the new valve installation in Post 23.
_____________________

My tractor is model L4310. It already has a third function control valve mounted on the rear fender. It is plumbed into the loader circuit.
I'm not sure what the valve is called, but it controls flow in two directions and automatically returns to center.

I have a wood splitter and a wood chipper that both use the tractor's hydraulics and hook up to the existing valve. Because of the return to center function of the valve, I have to tie it open with a bungee cord when I'm running my implements. I want to get away from the bungee cord and install the correct valve to run my equipment.

So my question is, what valve do I need and where can I buy one?

Here are some pictures of the current valve:

I'd say it's time for a new seat for sure.....lol

Do your splitter and chipper each have their own control valve with an internal relief valve?

Are you using the existing valve for any purpose now?

Thank you for your reply.
I don’t know if either implement has a built-in relief valve. I have very little experience with hydraulics. How would I go about figuring that out? Is there a visual check I can perform?
I don’t use the existing valve for any other functions besides supplying hydraulic power to my splitter and chipper.

Post some photos the of valves on the two implements.

It is confusing when you refer to the valve beside your seat as a third function valve.

I am assuming your loader valve has 7 lines connected to it and one of those lines feeds the valve beside your seat. is this correct?

The new format dropped Tapatalk support for loading photos. Please bear with me as I try to figure out posting photos.

In the mean time, yes, the existing valve has one line to the loader block and the other line goes to a valve body next to the hydraulic filter under the right side of the tractor..

@Dave_eng
Here are the photos of the valves you asked for.

SPLITTER:

CHIPPER:

VALVE BODY UNDER TRACTOR:
The line on the left closest to the filter (with the 90° fitting) runs to the valve on the fender.

LOADER VALVE:
The leftmost line runs to the valve on the fender.

This vid does a great job of explaining the types of hydraulic valves.

It appears you want a 4 way, 3 position Detent valve. My local Northern Tool has them in stock, but a quick web search will provide lots of buying options.

If you are interested in selling your current valve after you swap them out, shoot me a PM.

I was told to get a power beyond valve. From what information I found online, this looks like a conversion I’d need to do, or can I buy a valve already configured that way?
Or would the 4 way, 3 position valve eliminate the need for power beyond? Or is it already considered power beyond?

I’m not trying to be an ask-hole here. I don’t have much knowledge or experience with hydraulics but I’m trying to learn.

Your FEL valve that you are tapping into, and probably where you are getting the term “third function” from, is the power beyond port of the FEL control valve, and where your third function (ie grapple) would typically tap in.

In your setup, you only appear to have four hoses; supply, return, and two outputs. A power beyond has a fifth connection that supplies hydraulic power, well, beyond the valve.

Some tractors with factory rear remotes are plumbed in such a way that requires a power beyond valve. If what you have works and you just want a detent valve instead of a spring return, no need to re configure your entire system. Taking a few good pictures (manufacturer, and numbers on it, port configuration) of your current valve to any decent hydraulic shop (no, AutoZone, O’Riley’s, Advance etc do not qualify as a decent hydraulic shop) and simply asking for the detent version should yield adequate results.

The circled fitting appears to be a capped off power beyond fitting. No need to pay extra for a valve with a power beyond port just to cap it off.

What you want to do should be simple.

Buying a new valve with a detent will again have you using a banjo strap as when the splittler pressure increases to max, the detent on the upstream valve will just kick back to neutral. The detent feature will not remain engaged once system pressure has max'd out.

Why to you have the pressure compensated flow control in the system at the chipper? Too much flow or pressure?

I am thinking this Cross manual selector valve will do the job you want.

Unfortunately I cannot get a Cross link to insert here.

It has one IN port and then switches between either of two outputs.

I see one output being the feed to either your splitter or chipper.

The second output would just direct flow into your existing tank line from the valve to ensure you are not dead heading the main pump.

On the rear of the tractor you would have two quick connects. One tied into the tank or return line so the valves on the splitter or chiiper have a tank port.

The second quick connect is the out from the selector valve directing the pump line to the pump port on the splitter or chipper valve.

If you can be patient until sometime Tuesday, I will run my thoughts past the tech people at Cross Manufacturing to make certain I am not overlooking something.

That sounds great. I can wait a few days. I’ve been messing with the bungee cord this long, so a few more days won’t hurt.
I won’t be using either implement this week anyway.

To answer your question about the flow control valve on the chipper - it was installed on there from the factory.
You use it to adjust the speed of the feed rollers.

This might work now.

Thank you. I truly appreciate your time.
If you find out for sure it’s the one I want I’ll look into where I can buy one.

I have talked with Cross and their VS2 selector valve is acceptable.

They also suggested another alternative which I did not consider.

If you install the VS2 valve before your current valve, you then have the option of using that valve should you ever have the need.

The VS2 valve would have as its IN the line currently feeding the rear valve.... the power beyond line from your loader.

The VS2 valve has two possible outputs depending upon which position you put its control knob.

One position would be the feed to your splitter or chipper.

The other position would be the feed to your existing valve.

You would need to put a Tee into the tank line (reservoir line) on your existing valve.

This Tee branch would be the tank line from the splitter or chipper valve.

Their is nothing magical about the Cross valve.

Thanks again. I appreciate all of your help.
I won’t need the existing valve so the installation of the new one should be simple and straightforward.

Now to get my hands one.

Fun fact, Cross is based out of Hays KS, where I spent the first 24 years of my life. Small world.

Do standard detent valves operate in this manor? I thought only pressure release detent valves acted in this manor.
