Cessna 3 Spool Control Valve

[Dencotbi]

Hello,
This is my first attempt at using this forum, so I apologize in advance if I'm doing anything incorrectly here. I purchased this valve recently, probably before I should have without further knowledge of what I was about to do. I am looking at installing a remote valve for my Kubota L3200HST. I have been reading all I can find on the forum and I think I have learned quite a bit. Anyway I can't seem to find any information about this valve, and wonder if it would be suitable for my purpose. If someone know about this valve, I would appreciate hearing from you. The numbers I can find are 30913-2C. As soon as I figure out to post a picture, I'll do that.
Thanks

Here is a two spool Cessna valve.

Does your valve look like this but with three spools?

Yes it does look very much like that one. I have some pictures on my iPad and if you could point me to the instructions for uploading them, that would be great

At the bottom of the post, select go advance, and then select manage attachment and it will take you to a select screen,

Select one or more pictures and then select upload, and then select DONE, and then select post quick reply.

 

[Dencotbi]

Ok, hope this works.

The pictures came out fine.

I have to ask though, why purchase a used hyd valve not knowing what is does and whether it is any good?

If you ask your question on this forum, knowledgeable people will be able to help you and guide you to something that will work and how to connect it all together.

I see the OUT port label.

What is stamped by the other ports.

You might be able to connect it up and it might work OK, or not.

That is a good question and one I have been asking myself. I have a prince single spool which I purchased from Surplus City which should be delivered this week. I'll try to get the picture of that on here for you to see. My only immediate plan for the aux hydraulics is to operate a grapple which I'll be receiving tomorrow. I've read other threads in which you have shown this or a similar valve, 8 gal/ min. I just happened to also read threads of others who decided to put more spools for future possible use, and I saw this valve on Ebay. But I'm thinking that it might be stupid to risk using a used valve? I guess I am looking for the total concept help, and I would really appreciate your help.

Here is the rest of the valve data.

http://www.surpluscenter.com/_MoreSpecs/dr9-7861.pdf

Your tractor pressure is 2277 psi.

The valve comes set at 2000 psi, so you can match it up to the FEL relief setting.

Thanks. Do you think that this is the reasonable way to go? I realize that we are talking apples to oranges as far as number of spools. I just really wanted a simple, reasonably priced solution to grapple operation. I wasn't particularly sold on the diverter option, and that's why I started investigating adding a remote(s). I really think that one is probably enough for me. If you think this an appropriate valve, then I will just stick with that for now. Thanks for the guidance.

Yes sir, that valve will do what you want.

Be sure you install the PB screw in the C port and use that port to feed the next valve.

The PB from your loader will feed the new valve.

There is no reason you can not try it as a remote valve.

If it leaks or does not work as you want, then just remove it.

I'm trying to do the same thing - replace my 2-spool with a 3-spool to run a grapple.. so no worries there about your thinking

Besides, I think my 2-spool is bad as all 4 cylinders drop, so gotta swap anyways ..

 

[Dencotbi]

Ok, thanks. JJ. Just to verify that I have the installation right.
PB hose from hydraulic block to new valve inlet, PB screw into C port, then new hose from C port back to hydraulic block PB where first hose was removed, then hose from valve outlet to hydraulic block teed into existing return line.

 

[Dencotbi]

Good luck with that Midniteoyl.

That should work.

Can you post a picture of your hyd block.

 

[Dencotbi]

Here goes

 

[J_J]

If I remember correctly, the orange taped hose is the flow from pump.

White is the return /OUT flow from FEL.

The left port is the PB flow from the FEL.

That is my understanding also. Thanks very much for your help. I hope to receive the valve today. I just got through unloading my new grapple which was delivered this morning.
