Direction of flow from diverter valve

[k0ua]

It would seem to me, that if the regen position is the first movement of the joystick before the dentent to the right on the joystick, on the OP's tractor then that would go a long way to explaining the "weak" closing force he is currently experiencing. As his grapple is closing when the control is pushed to the right, and that is the regen position, then the closing force will be quite weak as fluid is being applied both to the cap and rod ends of the cylinder and the closing force will be cap force minus rod end force.. depending on size of the cylinder it could be just a few hundred pounds.

I think that is the situation I got. For now using as is....I'll give it a little time, but I may end up changing to a 3rd function, now that I have a better understanding. But you know...I did quite a bit of work Saturday. It does work, just a bit aggravating in the process.

jcummins,

Which part of your valve is the regen, first part of lever movement or to the far right?

I talked with the Prince hyd rep and his opinion is that the regen should not affect anything except a faster cyl.

For some reason I am thinking that the amount of fluid in the reverse mode will only fill part of the rod cyl and the hyd action will stop and go into relief.

So why is the cyl not moving or not moving correctly, is still a puzzle.

The cyl should work either way.

It has been suggested to remove the forth position, which is regen. I supposed you can just remove the cans on the bottom of the valve and remove the regen parts.

I'm not sure on when in regen. From your description...I think...regen is when it goes slow with power, and when fast without power. Regardless if left or right, initial movement is slow, the harder you push the faster it is....and it seems more power too.

I worked a couple of hours this morning. Starting to not make the mistakes of opening/closing when I want the opposite. It may just be ... I got to get use to it.

Regen is always faster because you are combining the fluid from the other side of the cyl with the pump flow.

What part of the FEL are you in when the bucket dumps fastest.

On some valves the regen is at the far right, and there is no reason to go into regen when you want power mode.

If your regen is at the front part of the lever movement, you will be dumping the bucket fast mode. If you want power mode, you move the lever more to the far right.

Regen is the fourth position of that spool.

Regen is a position on the spool where the B port is closed off to tank, and that forces the rod end fluid to combine with the pump flow. providing a faster action but less power.

That is the best I can do to explain regen.

The farther you move the joystick both left/right the speed of the action is faster. So regen is far right.

IF regen was the issue, then just barely moving the joystick with the valve activate should have done something...and it did not. But regen is somehow the apparent issue.

There are 4 good size trees covered up in that biggest pile. A stump dug up by a counties backhoe in the far pile....which I can roll but can't pick up. Without the tractor it would have taken me weeks to a month. With the tractor no grapple, several days, and a lot of physical work. Tractor and grapple, about a day....and this old man isn't wore out.

What you said is the way any valve works.

The further you move the valve , the faster the hyd work. You will have equal speed in curl up as curl down, unless you go into regen.

Regen is different.

For instance, whatever speed the curl up works, if you go into regen, the bucket dump will move twice as fast.

Nice job JC, good to see your moving forwards and working the machine, this will all be a distant memory and the grapple action will be second nature after a few more of those piles.
