question about hydraulic valves

[WilcoKubota]

I believe it stands for Top Link and Tilt - a hydraulic top link and side arm tilt on your 3 point hitch. The hydraulic top link lets you change the angle of your whole implement front to back and the tilt cylinder for one of the side arms lets you change the side to side vertical angle (tilt).

Thank yoy for the information.
You've also a nice site with some interesting pics.

Thanks, it is an unusual tractor and fun to modify.

Hello,

I've been thinking, and can I put it together this way?

Anyone who can help me?

If your new valve had a PB port, you would not need the ball valve.

With a normal FEL valve with PB, and no lever activated, the fluid just flows through all valves and then to tank. Flow path = pump to FEL valve, out of FEL PB port to 3pt. Return hose to tank

You can activate any valve and have flow to that circuit just by moving the lever.

If you have a 10 GPM flow and the FEL is only using about 5 GPM, then the other 5 GPM is available for the 3pt.

Yes, your ball valve would work as long as you did not shut off the hyd flow. If you deadhead the pump, it may burst. You could put a relief valve in front of the ball valve.

This valve is what you need.

@J_J
Yes, I should do it that way, but i cant find any online shop here who sells anything like that for not ridiculous high prices.
I would do what you say, and put a relief valve before the ball valve.
When i'm done i will post some pic's of it.

Thank you.

Where you show a 3-way ball valve should be a single selector valve like this:
Surplus Center - 1/2" NPT 20 GPM PRINCE SELECTOR VALVE
It is designed for that function and will not have a dead zone.


You really will be better off with a single multi-spool valve that has power beyond. Take your time and shop around for a good price. You won't need it until your loader is complete. When you break it up into multiple low priced valves the cost for extra hoses and fittings will usually eat up any savings in valve prices. Put together a complete bill of materials to compare options and you will see what I mean.

I've removed my side fender to see what's possible.
at my first glance I saw that a ball valve is impossible right next to the pump, and i don't see a place where I could it else so I should buy a valve with PB.

here are 2 pictures of how it is.

the flexible hose is the prssure line, at the bottem of the pump. at the top of the pump is a hard line and thats the suction line. There is a rubber tube on it, probably a leak of the previous owner.

on the second pucture you can see it with the protection before it.

You would be wise to get the valve with PB and install it and run the return port to tank, and Install the PB plug to connect all the hydraulics.

If you don't have the loader yet, just plug the work ports.

With everything connected, you should have pump to IN port of FEL, FEL PB OUT to IN port of remote valve, and out of remote valve PB to 3pt IN port.

All returns hoses go to tank.

If you don't have remotes, or will not use one, the PB from the FEL goes to the 3pt.

You could also put QD's in the work ports of the FEL, and just plug in the hoses when you get the loader.

Once the loader is connected, check and adjust the FEL relief and set it to about 50 to 100 below the pumps max pressure.

To know the pump pressure, should I tee in a gage to the in port of the valve?
