Choosing a Control Valve for Rear Remotes

[threepiece]

I was very lucky to find these two valves at the scrap yard recently. I have been studying valves but am not confident enough to make a new purchase. The blue one, a Vickers is tagged “good take off” the black Husco appears to be unused.

I need open center control to operate top, tilt and scarifier cylinders for a scraper box on my JD 110TLB.

The black Husco seems to have no detent on one of the spools. The spool slides evenly through the stroke with no interference. Is this a defect or possibly intended for some application?

I would very much appreciate any help in confirming if any of these control valves are suitable for this. Thanks to all for any help.

Why not just buy a simple two spool valve? I added this one to my Kubota and it works great.

Dan,
I presume the Husco valve was a spring center spool where you either push or pull and it returns to center or home position. This is common but what you don’t know on either valve is the type of spool nor if those are open center or closed center valve assemblies. Could be cylinder or motor spool.

Are any of the ports labeled on those valve stacks?

Valves also look like would have a flow capacity significantly greater than what you require.

A picture of the nameplates would be helpful.

Looks like a 110 TLB should flow 23.6 gpm.

Yes, I may do that however I could not resist these valves at $4 for both. The 3 spool valve from Summit is over $360.

Yes, I think the flow is sufficient on either valve.

On both valves, when I blow into what I presume is the T or P ports my breath flows freely. Is it safe to assume these are open center?

What has me suspicious about the Husco is one of the spools. It does not have a detent nor is it spring loaded The spool slides freely. It stays in position where it was last moved to.

The Vickers valve has no data plate, only numbers cast into the body

If you blow into the P port where does the air exhaust at? I don’t smoke but this is an area where if you blow smoke into a port it makes it easier to see where it comes out. Then have to look for any identifying marks by those ports.

That is concerning, not sure what type of spool control that would be.

The Husco is a series 5000 but the configuration numbers are proprietary so no help there. I can't make out the letters and numbers below the Vickers emblem.
That might be the model designation.

I have all but given up on the Husco. The numbers near the “Vickers” is a patent number.
I plan to “blow smoke” of sorts through the Vickers valve, this while operating the valve. I hope to gain a clear understanding of its operation this way.

I am in the process of creating a control lever to attach

 

[threepiece]

With a control lever installed, I need to determine which is P and T ports. I see no identification other than the type of fitting or what appears to be a bleed screw on the top of one.

Is it possible these ports are interchangeable? Can a valve work equally well when flowed in either direction?

 

[threepiece]

What I discovered so far:

The port without the bleed screw passes to the opposite port with the bleed screw only when the control is at rest. When the lever is moved either direction flow is stopped through this port.

The port with the bleed screw passes to the opposite port at rest. When the lever is moved, flow is stopped to the opposite port (without the bleed screw) and diverted to a work port in that valve. Is it safe to assume this port without the bleed screw is the P port?

 

[oldnslo]

No you can not switch pressure and tank on that valve. The tank port s probably rated for 350 PSI or less.

My guess would be pressure is in the center but that is 100% pure guess.

What size are the ports on that valve? I might have an old Vickers catalog on some of their mobile valves.

Interesting thought about the P port in the center. I had not considered this. I will investigate.

Have you read my post #13? I suspect you missed it.

This looks like it may be your valve series. Look at page 7 for port identification.

This was helpful. Using the dimensions on the part drawing I was able to “believe” it is a CM11 series valve and not a CM2 series. I need to look more carefully for an identifier. There are several 1/16” characters stamped onto the surface of some of the blocks.

Also, I was able to see the control lever configuration. Theirs is one piece while my design is four pieces.

 

[threepiece]

I was able to decode the characters stamped on this Vickers valve. CM11NO1 R20D as follows:

CM11- series
NO- no modifications
1- describes the thread size of each port
R- standard relief valve (partial flow bypass)
20- system relief valve setting (2000psi)
D- double acting
