Valve question

tomf · Mar 8, 2009

You're right. Once I get involved in something I hate to give up. Of course the valve at which I was looking jump in price $100 since yesteray. LOL said with sarcasm. Don't get me wrong, I really appreciate what you and everyone else does on this site and others. I love the way the INTERNET has spread knowledge that previously was unavailable.

Maybe someone will recognize the mount or valve of the specific application and tell us what's up.

Thanks again, Tom

Could air getting into the system at one work port be the cause of my problem?

The reason I ask is that yesterday and the day before when I hooked up the blade to the bucket ports I could angle in both directions. Yesterday I sealed the quick connects and the hose line with locktite. Now I can only angle in one direction because of the regen feature of the bucket spool. I thought it strange that I could angle in both directions but the loader arms would only move in one direction when hooked to the bucket spool.

Everything should purge itself, there is no need to bleed any lines.

Boys what I see when looking at his picture. I see a hose going to the in port, a PB hose and BP plug, a QC on the A port, a QC on the out port and I don't see a hose to the tank or a B port where it should be. I looked at the plow and it has a double acting Cyl. I think the valve is for a single acting Cyl. and Tom is trying to run a double acting Cyl.

LeeJohn. The picture you are looking at is just for identification of the valve. The IN of the blade valve is not visible in this picture. In this particular picture I have the cylinder blade hooked to my loader bucket spool. I was testing the cylinder trying to isolate the problem. The problem lies at the B port. Right now I suspect that B port is open to the TANK in neutral. Sauer-Danfoss says they can't identify the configuration based on the identifying markings, contact the dealer. I've emailed my local Kubota dealer today so hopefully I'll have the valve configuration soon.

Anyway the valve is plumbed like this.
PB of loader valve to IN of blade valve
OUT of blade valve "tee-ed" to OUT of loader valve to TANK
PB of blade valve to IN of tractor hydraulics
Quick connects on the blade valve work ports which are quick connected to hoses of the blade cylinder.

Here's a picture of the valve in the state I bought it. If you look closely you can see the IN port. If you zoom in you can see the letter N above the IN port and the word OUT above the OUT port.

Just as I suspected, SD OEM'ed it for Kubota, and they cannot/will not provide specs...Husco does the same thing.

I wish you luck getting any info on it...

BUT-What info could they provide that would be beneficial at this point other than to satisfy your curiosity? It is not working for what you need...

Tom I have a Danfoss valve about 10gal prm, it has the A & B ports on top with load checks. No handle. Its for double acting cyl. I well check tomorrow and see if I have the Pb plug. I think I gave $20.00 for it + the PB plug. I had it on my B7800 and took it off and put on a double spool for 2 remotes, and I might of used the PB plug for it.
If I don't have the PB plug the one you have might be the same. I well sell it for the $20.00 I gave for it + the shipping about $8 or $9. But let me check tomorrow and if you are interested let me know.

Tom the valve I have looks like the one on page 15 of your PDF file or model 1617. I think the A & B ports are #6 sae O ring fittings. In & out might be # 8 sae O ring fittings

LeeJohn. I'm interested. I sent you an email. Thanks Tom

After a couple of email exchanges with my local Kobota dealer explaining the situation, here is what they said

"The blade and valve that you have were originally for a commercial front mower. The valve circuitry should be similar to your application, so I I would also suspect that valve is the cause of your problems. I would suggest buying a new valve that fits your needs better."

I think I have exhausted all my other options so that's what I'm going to do.
