Thank you for your input! I have enough time to research any options. My problem is that I am just learning and I do not understand much of the terminology. So it looks like
surplus center does not have any solenoid valve with PB output (which I need in order to feed any future remotes right?)
Another option will be to replace my FEL valve with a 3spool valve that has a PB for the remotes, am I right?. And that option also looks temping. since I will not need any switches, and a lever is easier to control than just a switch.
(The funny thing is that 2 days ago I didn't know what the OC, PB even meant!) hahah
Replacing your existing valve would actually be a pretty major undertaking. Your valve is cable operated, don't think there is a 3 spool cable operated valve (what would the 3rd cable be operated by?) So you'd probably have to end up creating mechanical linkages not to mention moving the location of the valve and re-routing hoses.
As for Power Beyond - to understand better you need to understand the basic path the hydraulic fluid makes in your tractor. This is typical & oversimplified so yours may differ slightly somewhere but it will get you in the game (so to speak)
Tank -> Pump -> Power Steering (if not fed from a separate pump/output) -> Loader Valve (Lift/Lower function then Dump/Curl function then out the Power Beyond Port) -> Rear Remotes (SCV's) if present -> 3 Point Lift -> back to the Tank
This is how things would flow in an open center system when NOTHING is activated. Any time you activate a valve (Loader, 3pt lift, or rear remotes) the flow is diverted from that path into the cylinder(s) you are operating.
Your 3rd function solenoid would go in this loop between the loader valve and the 3pt (or rear remotes). The Solenoid sub-plate will not have a separate "power beyond" port but rather an IN (or P/Pressure port), OUT (T/Tank port), and two work ports A & B.
Why not go with
this valve, so with sub plate and the Hirschmann Connectors the cost will be $200. Add a hand grip switch over my existing joystick and I am at quarter the cost of the WR long valve? What I am missing here?
Just off the top of my head . .
2 long hoses from the valve to the front of the loader
2 shorter hoses to put the valve in series of your power beyond line
various couplers
various fittings
mounting plates that you will have to fabricate yourself or have made
Misc wiring to get power to your solenoid along with connecting the switch on the grip to the solenoid
Having been down the Do-It-Yourself route I can honestly say you probably *could* come out a little cheaper however there will ALWAYS be something you forgot, overlooked, mis-measured, etc that will make you have to re-do something. That's the extra value from a pre-made kit. The headaches, gotchas, and "learning curve" of design on the fly has been removed from the equation.
Here is the thread I did on my build - thanks to photobucket the pictures no longer work so I created a Rev 2 version and put it into a PDF
www.tractorbynet.com/forums/customization/358086-kioti-ck-35-3rd-function.html
You can read thru the thread to see the discussion & feedback and my Rev 2 PDF document is linked on the last page of the thread.
FWIW - If I had it to do over knowing what I know now; I'd still build my own because there are things I didn't like about the WR Long kit & things I did that aren't included in the kit. Not to mention I now know a LOT more about how my hydraulic system works.
I am by NO MEANS an expert on the subject but I would suggest you to read thru the PDF document and see all the places I "messed up" and decide if this is a road you really want to go down. I'm not trying to talk you out of it, I just want to make sure you really understand what you're in for.
Best of luck whatever you decide.
