Loader Valve Recommendations?

[K5lwq]

On your first post you stated one of the reasons that you are looking for a different valve is that your current valve has no load check. Why would you consider another valve without load checks?

Did you look at the Bucher HDM11S series? It appears to offer load checks on each section. I did not look at all the other features or options though.

Would also suggest contacting Prince since there two section loader valve has load checks for both spools. Three section might also.

No load check is a issue. My valve has none at all. These valve have at least one main check. The Nimco has one on each spool but no adjustable relief.

I did look at the Bucher HDM11S, but it has Load Sensing. I don't know how that will work on a constant flow style pump. From what I read, it needs to be used with a variable displacement pump, is that correct? I also don't think it can have power beyond. I have learned some, but still not sure about certain things.

I have called and sent info to 3 different companies, and still no reply.

I am open to any suggestion and appreciate the feed back and info.

Did you have an issue with Nimco valves? I thought I read that in some of my research.

I believe the Bucher can be configured for either open center fixed displacement pumps or closed center variable volume pumps with or without load sense. The data sheet is a little confusing and I have not studied it thoroughly

Yes I had a Nimco CV112 on my Branson when new. It had zero metering when lowering a load and next to none when dumping especially with forks on. To me it was unsafe to operate so I replaced it with a Prince loader valve. Prince isn稚 perfect but much better than the Nimco. I presume that Nimco must work for other people since I believe Massey has them on some models

Have you tried contacting any distributors in your area? They might respond better than the OEM.

Two of the ones I contacted are in Texas, not real close to me but I did offer to come talk to them in person. I will look for more around here. It is a challenge to find a valve in this size with the features I want. Thanks again for your help!

Thanks Dave for the advice. I have looked at cross before but can't find a three spool valve at all.

They make them, I have one I installed. I also have installed a 2 valve Prince, seems to be a decent quality. Not as heavy duty as Cross, but good.

I didn't see them on their website. Thanks for letting me know, I will just call them today and see what they have.

I talked with Cross today and the only way they can get a 3 spool is a large valve and 30 GPM. The dimensions would put me outside the footprint of the tractor. The hunt continues.

Update. I narrowed my search to either a Bucher or Nimco valve. I called Nimco and received 0 help. All the lady would say is they would email me some information. I finally talked with their distributor for Texas and although he was polite and called me back, he said that Nimco is not very helpful and I probably would not get any answers from them. Also they are now closed for the next two weeks. So that leaves Bucher.

Thanks to Brian at Fit Rite, I was able to talk with the folks at Trausch yesterday and they are researching what they can build and are going to call me back.

What I have learned through this process is people that sell hydraulic valves are not that interested in selling one valve to an individual. I have called close to 20 different companies and have heard back from three. Of the three only one, Trausch, seems willing to sell me a valve. You would think this would be a much simpler process than it has turned out to be. :confused3:

Probably quite true. I have always done my own research.

Unfortunately most distributors and OEM's are running on skeleton crews and don't have the time to devote to researching a single valve assembly like you are asking for. Also a lot of distributors carry so many product lines that it is next to impossible for a person to know what valves are available.

Hopefully Trausch will bill able to assist you in your quest for this valve.

I got the Bucher 3 stack valve for the rear remote project on my former L3200 from Fitrite. I was happy with it. Not quite as good as the loader valves on either of my Kubotas. But orders of magnitude better than the leaky crap valves Kubota is using for the rear remotes on the Grands these days.

The butcher valve was letting my TnT cylinders creep a few inches a day, which is perfectly fine. My current metric on my Grand is 1-6" an hour. Neither loader moves noticably in weeks.

Thanks everyone for the help! I have been researching different valves for a month now and see a few options from different manufacturers. The problem is the spec sheets I have found are not always clear. For instance, the Bucher sheet is not clear if you can get the joystick on the float spool. That is what he is having to research.

Another interesting thing is Bucher says their internal leakage is 6 to 12 cc's per minute. That is a wide range and fairly high. However, they say lower values are available upon request but you have to speak to one of their salespeople.

The Walvoil SD5 has everything I am looking for and would order if I could. I contacted two different salespeople and drove to one location in Dallas and still have no information on how to order one. It just seems odd to me.

Maybe I will hear back on the Bucher valve in a couple of days. If not, I will follow up with them on Friday.

Not sure which Bucher valve you are talking about, but my L3200 install had 2 float valves on a joystick & it came from Fitrite. I don't think the 3rd had any detents or anything, but I didn't use that one much.

This is a PDF of the valve I considering. I will be mounting it ports up and the float spool I think I need is the WW. I believe that will give me float when I push the handle toward the spool. If you read the foot notes, it states you must use positioner 240 and lever L192. The joystick is L218. Maybe you or someone smarter than me can look at this and tell me if I am thinking wrong.

I did follow up with Trausch yesterday and they still have not heard back from Bucher. Seems I am not the only one that has a hard time getting information from valve manufactures.

The actual spool itself must be pushed into the valve body to go into the float position. So when you push the lever towards the valve body, that pulls the spool out.

As far as manufacturers not getting back to you. Any manufacturer that is set up to deal in volume looses money talking to anyone that only wants 1 or 2 items. Doesn't matter if you buy the item or not, they have lost $$$ simply by talking to you. Just how it is.

Why do you need a mono block valve, why not use a stacking valve? Size related I'm guessing. :confused3:

Size is the limiting factor. I am not saying I can't find a way to make a stack valve work, but a small mono block would be a easy replacement.

Are you saying that the spool I am looking at must be pushed into the valve body to go into float? This is where I get confused. There are two float options, Z spool and WW spool. I want float to be in the direction of lowering the loader, don't I? At least on all the loaders I have used this is the case.

 

[MtnViewRanch]

I am not familiar with what a Z spool or a WW spool are.

Yes you want the float to be at the end of lowering the loader throw. But the valve may have to be turned 180* to get the movement of the lever in the correct direction to be able to achieve that.

 

[oldnslo]

Looks like the Z spool is standard float configuration since the WW requires a special body.

Also looks like on the valve the joystick pivot is below the spool so pushing the lever would push the into the valve body.

Just have to connect the hoses to the correct ports to get the direction of movement required.

I agree the Z spool is the standard. However, if I am understanding the schematic correctly, float is achieved by pulling the spool all the way out. So pushing in would be position 1, flow from work port A to B. Center would be no flow to work ports. Pulling out to position 2, flow would be from B to A. And pulling all the way out would be fourth position float. If this is correct, I could not achieve float by pushing the lever toward the valve. Although I could swap the hoses, I would be pulling the lever to lower and go into float.

If I use the WW spool then 4th position would be when spool is pushed all the way in which allows for the lever orientation to be correct. Also, no check valve is available on the Z spool but is on the WW spool.

Am I understanding this correctly?

 

[oldnslo]

K5,
Like you say the data sheet for the Bucher valves is confusing but I believe the standard body has the load check option. This is based on the fact that all of the schematics in showing multiple spools have the load checks in them. Adding float does not change the body configuration in most cases so I suspect the Z spool would have the load check. Agree that the individual spool schematic does not show this but neither does the A spool which is the 3 position variant of the Z spool

Yes you are correct in the the WW would have you moving the joystick the wrong way to lower.
