Flow control

[yotehunter66]

I have just installed my grappler on my loader bucket but need to slow down the speed for opening and cloaing. Both way to fast. Would it be best to install two flow control valves or one flow control valve that restricts in both directions?

one in the rod end would prevent the grapple from free falling while closing and also control the opening speed.

Cool thanks.

Cheaper than a flow control valve is to use a plug in line and drill a very small hole in it to allow a small amount of fluid to pass thru.

It all depends on how you want the grapple to operate.

Slow in both directions or slow in one direction and fast in the other.

$4 at TSC took care of the problem slowed it down both ways so it stopped slamming. Thanks for the help!

Remember that any oil being bypassed to return creates waste heat.

Any restrictions increase line pressure and fluid velocity as the pump still tries to force the same amount of oil through the smaller diameter.

Not saying it will hurt anything, but you could prematurely wear out your oil or lines.

I'd find a nearby hydraulics shop and ask them if whatever you did with TSC parts will hurt anything.

I deal with hydraulics as part of my job, and anything that only cost four dollars gives me the heebie jeebies.

If $4 part gives you the heebie jeebies, then my fix for controlling the drop speed of my wood splitter wedge would send you into shock. It might of cost me $0.15

I don't think I'm going to worry to much as this isn't getting used on a daily basis and for hours and hours on end. Regardless of how I do it, while other ways may be more ideal, it will cause a restriction which will cause what you are describing. Just my thinking I guess.
