Diverter opinions

Steve_Miller · Jul 7, 2006

I'm installing a diverter valve and would like to know which function would be best to tap into, the curl or the lift circuit. I have a Kioti CK20 and have already bought the diverter and a bunch of fittings. I have it all mapped out where I'm going to put the diverter and the outlets it will feed. My only question is which function to break into and the pro's and con's of each. I am going to have three sets of outlets for this diverter function. One will feed my grapple on the FEL, the second is at midway on the left hand side of the tractor which will feed my side wing for pushing snow back in the winter and third will be at the rear for a chute control for my snowblower and also my top link cylinder. I'm leaning towards the lift circuit as it has the float position which is good for the side wing to be able to float with the ground when plowing and also the top link (which I can't think of what it would be good for but it can't hurt). Gone for the weekend , but will check back in on Monday.

Thanks in advance
Steve

Tap into curl, that way you can still come down on what you are trying to pick up as you close the grapple.It will get to be second nature after a short while.

The most common is to tap into the curl, but I can see the advantage of the float for your side wing plow...
So why not use quick couplers to hook it up? Then you could switch between the lift and curl circuits at your leisure. Mine is plumbed this way, although I have never needed to switch it.

Keep this in mind though...The float will only work on the circuit that is "active" through the diverter, because the diverter blocks the other ports.
Example: You are plowing with the front blade in "float" mode, the you switch the diverter to lower your side wing and "float" it. Because the ports for the front blade are now "blocked" by the diverter, it is not "floating" anymore, and when your switch back to the front blade, the side wing now is not floating. Make sense?

Here is a link to my diverter install, may give you some ideas..

Perfect sense Kenny, this is why I like to ask as there is always something I can never think of.

Thanks

That is great that you are setting up three remote pairs from the diverter. I bet that will look like an octopus. With the curl function on our Kiotis you get the regenerative dump so a really fast open or close on the grapple.

You're being innovative.

Any hydraulic guys out there that have seen a lot of #5 JIC fittings and a thread that is so close to 3/8" NPT but not exactly the same (I'm guessing something metric). I've run into these through my fittings on my CK20. This was not done by a hydraulics person that is familiar within bulkhead fittings from what I've seen so far.

A #5 JIC fitting is actually has 1/2" x 20 straight threads. A 3/8" NPT has 18 threads per inch with an outside diameter of .67 inches and is tapered.

A 3/8" NPT male fitting will almost completely thread into a 3/8" BSPP straight female fitting.
