Stack valve regen

[MtnViewRanch]

Your hydraulic knowledge must be vastly superior to mine, you still have me very :confused2:

I bet I'm not the only one either...

I can't argue with glastron23 . :confused3: :confused2: What I DO KNOW is that the majority of the tractors talked about on THIS forum have the loader regen system in the loader control valve.

It is possible but it will take some more components.

The regenerative circuit can be operated with two normally closed solenoid valves and a check valve.

Description at bottom of PDF.

Thanks alot guys for clearing that up. My head was getting sore from hitting it against the wall. Yeah im up in air on the quick dump but I do recall wishing I had it in certain situations. Thanks again. Its forums like this that make life soo much easier. Im a big hot rod guy and have a shop and just now getting into the tractor side of things and very impressed with the simplicity and design of them. Def see how it can become another hobby all by itself. Have a good one. GARY

thats OK guys.. regen is hard on the head at the best of times.. the Sun YDCD-LHN is a fine circuit to use, check on page 2 and the 10 or 15 GPM units will do the job, these are easy to plumb in with a regular valve, they can have holding properties and they shift to full cylinder power when the extra flow difference is not going to help the cylinder speed due to the load, read the first page and this will help explain the concept.

Gary, just a warning in general. If you get into the tractor thing, you will just about forget about the Hot Rod thing. (I think I use to to that stuff, don't really remember though??) :thumbsup: Commonly known as Tractoritus and as far as I know,there IS NO CURE know to mankind. :cool2:

I'm just sittin here reading & learning, but it sounds like it can be handled either way? in the valve or the Sun valve/piping as suggested by Glastron23? That Sun set up looks like it would provide this fast dump regen an any valve. Yes, no?

Also just reread my first post and realized it sounded like I wanted float up like jj pointed out but the words justz ligned up wrong (operator error) and def know its the float down control for up and down fel operation. And I happened upon the both manual and 12v prince valve by mistake but figured it would be nice to have the electric swith on joystick for basic operation and manual lever available for any feathering I might desire to do. Thanks again guys

Yes, the sun module will add regen to systems when this is not an option in the directional control valve. It does require external plumbing and I doubt is used on the vast majority of tractors since most valves designed for FEL use have this feature built into them.

Like glastron stated: The Sun modules offer some other options like load holding, automatic swith over from regen to full power dump (pressure operated) and are placed at the point of use to reduce the high line flows going through the directional valve.

To the OP: Some companies do offere both mechanical and electric control of the same valve stack. I do NOT know if the prince stack you are looking at offer this feature.

Look at the bottom of this PDF and you will see the hyd circuit for external regen operation.

For most people regen is a special spool that includes regen. The regen portion, essentially routes the the rod end fluid to the base end and also shuts off the return path to tank.
