Power Beyond Sleeve

[Gregster613]

Hello Hydraulic wizards, I have been having on-going problems with my TYM Nimco loader valve and I found a Nimco distributor with a matching number valve to fit. It looks almost exactly the same as my old valve - which is not available through TYM - says Jordon's tractor.

The end caps with the float for loader and regen for curl/dump look different but have the same functions. I added the schematic as an attachment to this message. I plan to order the valve but when I asked him to add the power beyond sleeve to the order, he asked me to send him all the info about the PB sleeve and he'd see if they had it?

What info would he be needing to have? I've never seen a PB sleeve, the one in my current valve was installed by my dealer's mechanic; I'm hoping it will interchange with the new valve but to be sure I had what I needed on-hand when I do the replacement I asked him to send me a PB sleeve along with the new valve, and I get questions from the distributor about the PB sleeve??

I could sure use a touch of guidance here as I'd really like to get all the proper pieces at one time/shipment. Or is a PB sleeve something you get separate from the valve itself?? Do I need to search out a hydraulic shop to source one? I thought that a Nimco valve distributor would know all about this stuff but perhaps I'm wrong? I do know that I'm not the most knowledgeable per hydraulics but I can change out a valve and if need be get longer or shorter hoses, or different style adapters if needed. I don't know much about the PB sleeve except what it does and is called. Maybe that's what I did wrong - called it a sleeve?? - is it called something else?

Please view the attached PDF and correct me if I have my terminology wrong and point me in the direction I need go to get a power beyond fitting that fits this new valve. The PB feeds my 3 scv's then continues on to the 3ph and tank. Thanks for guidance. Greg

Please send me all the information off the power beyond sleeve and I will see if it is something we can get.

Where you are being fooled is in the use of a different term with the same meaning as Power Beyond.

The term High Pressure Carry Over is more of a European term and is identified as HPCO which is item #8 in your pdf file

Dave M7040, Thank you for the reply and for the definition of the mysterious HPCO which I now realize means high pressure carry over. I probably am using incorrect wording speaking of Power Beyond while replying to a salesperson. I am the first to admit I didn't know what HPCO meant! There are many various terms used to describe the same items in Hydraulic speech! I kinda thought it meant high pressure, but didn't get the carry-over. Which could also mean "Cross-over"???
P2 crosses directly to T1 if I follow along right? Is power beyond a sleeve that plugs into T1 or T2 and just re-directs straight power to the rear??

I studied the schematic numerous times today and after comparing it to my current valve on my tractor I believe that my power beyond sleeve/valve is an sae 8 sized plug that screws into the port and has a sleeve inside it which re-directs the power path to my rear scv'c. and 3ph. i can deal with that easily, what i can't see from the schematic is whether there are internal threads inside the replacement valve or not. That was the main reason for my question to the sales rep in the first place - will I need to buy a new HPCO plug/sleeve or will my existing one work?

From the schematic Isometric view - the top left side sae 8 port is my current in feed port - directly across from that is another top side sae 8 port which is my tank return line - directly below that port (exiting to the side - and unseen on the view) is another sae 8 port which feeds my power beyond line. This tells me that my current fittings, lines , etc., etc. will fit and work perfectly! Except that i cannot see that side of the valve and that lends me to guess!

Thus i asked the seller/manufacturer of the valve to send me a new power beyond sleeve/valve/plug. I don't think it's really needed but I wanted to have all the parts/options available when the replacement was to take place. Which will take 8 - 10 weeks for the valve to appear in my mailbox - thanks COVID-19!!!

Dave, I really appreciate that you took the time to address my original question and if I haven't annoyed you too much yet - another couple of answers will be greatly appreciated once again! I hope from my lengthy explanation that you can figure out the path my questions are leading to. IE...are my P2, T1, T2 estimates correct? Is that the correct flow path to follow??
Thanks ever so much for the guidance!!! Greg

I am not a master of hydraulic schematics like a few old members.

The cost of a sleeve will be less than $50 and with it you get the new O rings to seal it internally and further have something that you know is made for the new valve.

I think the sleeve has internal threads which become the power beyond port. Identified as P3 on the schematic. You will remove a plug, screw in the sleeve and then the power beyond hose will screw into the new sleeve.

If you look in the lower right corner of the drawing just above the Title Block it shows the pressure limitations of the T lines which is 145 psi. So any T port is not involved with HPCO as the H stand for High, i.e.. much more than 145 psi.

Ask more questions if this is not clear and later today I will have more time to go to the NIMCO web site to look around.

I looked over literature on the Nimco site.

The HPCO sleeve screws into the T1 port. T2 must be routed to the reservoir.

Thanks Dave, That's the info I was trying to get figured out. The HPCO adapter must be what we in the rest of the world call a power beyond sleeve. I know that I've never actually seen one outside of the valve before. Now I just need to send the proper name for the adapter to my source at Nimco and see if that makes the difference in understanding we were having disappear. Although I am still wondering if Part # 8 isn't already an power beyond adapter? The schematic doesn't make that part clear.

I have trouble navigating the Nimco site. Would you send me the link you used to get that picture of the adapter and the literature about the ports? If I can get into the right place I can download info that may be useful. I'd like to get all the info I can per the valve I'm planning to purchase, so I don't make any dumb rookie mistakes.
Thanks for all your help so far!! Greg

This is the link.

In most cases manufacturers sell the PB or HPCO sleeve separately to keep their prices low to be competitive

Dave, Thanks for the link but it's not the correct valve. It is a CV112 but it's not the cable operated type that I need. I tried searching for 11087-2Sa but got nowhere. That is the valve shown in my schematic and the one I need. Could you possibly help me get to the proper directional control valve? Thank you.

Greg
Look at this page from Nimco's site which shows the CV 112 is available as a cable control option.

Are you dealing with and getting advice from the Nimco head office tech people or just someone who sells their products?

Here is a page showing the cable control available for a number of Nimco CV valves including the CV 112.

The Nimco order forum which is also attached is the critical aspect of ending up with the valve you want.

Each box on the forum contains critical details which will make your loader operation a joy or drive you nuts.

I suggest you invest in a phone call and ask to speak to someone at Nimco Headquarters who can help you spec the exact valve you need.

Armed with the detailed order form info you can then go to whomever you are ordering the valve from and tell them exactly what you want ordered.

Local vendors do not have the knowledge of one brand's products to get you the best valve for your needs. They sell many different brands to a wide variety of customers and you do not want to rely on their knowledge too heavily.

Thanks again for the help Dave! I found that info and particular page (#15) last night, filled out all that I was sure of (including wire control) and sent it out. I have a confirmation page back from them this morning.

The person I've been e-mailing per this order is the same person whom I originally connected with and provided me the schematic for my original TYM valve #11087-2S. I've said "repeatedly" that I want the same spec's as TYM uses and since this company built the valve initially for TYM they should have access to that info already. The only item I was concerned about was the power beyond valve because I was unsure if my old one would transfer over - which I believe will - then I see it is listed in the last block on page 15! As an HPC-fitting (Power Beyond). I got slightly stumped when he asked 'me" for numbers about the valve. Guess I was using wrong terminology.

On page 15 the only things I didn't know for sure how to answer was the spool type - so I asked for what I have now Raise/Lower = DA + float so in Section 1 I put code 3X. For curl/dump in section 2 they only had DA + regen w/metering [I assume this is the quick dump function?] they listed 8R and 8S but both say the same thing so I have 8R in my copy of the sheet but in my e-mail I said whatever TYM used is what I wanted. I put in all that I knew of and feel okay with what I ordered, specifically since I asked several time to have whatever spec's TYM uses. It should be pretty much a plug and play event once the valve actually gets here.

What did through me off for a while was the Series CV112 valve reference - my current valve is listed as 11087-2S and that's what is in the bottom right hand side of the schematic I was sent when I asked if they could replace my valve. All these different #'s and specific hydraulic speech kinda make me dizzy getting through this! But I will chug my way through and get a new valve eventually. I'm getting closer each time. Greg
