Another Power Beyond Question

[daBear]

I am adding a second two spool joy stick controller to my existing TNT setup. I think I am correct on the connections and would like a second opinion. None of the cylinder control hoses are shown for clarity, just the hoses from the front hydraulic block to the A and B valves. The black and red lines on this pdf are existing. Blue and green lines are what I think are correct. See what you hydraulic experts think or tell me what I am doing wrong as I am not a hydraulics expert at all.

Close, but no cigar...see my changes in green. The "return" fitting on the tractor feeds the 3PH, so you have to feed it from the PB of the second valve. You can Tee the two tank lines together.

Thank you sir. I will clean the drawing up again tomorrow at work and repost for your review when possible to make sure I understand it. I will never figure hydraulics out, but sure do enjoy using them.

Thanks again, Alex, aka daBear

You are welcome Alex

Ok, back to hydraulics for Dummies. I have revised the drawing and ready for the final review to see if I have gotten the connections right this time. Thanks you your help and assistance.

The hose connections are correct this time, but you will need the PB sleeve in the second valve...only the last valve in the circuit does not need it-and that is already by default the 3PH (rockshaft valve) In fact you can't even hook the hose up to that port without it as the "sleeve" is the connection for the hose, otherwise it's just a blank plug.

Clear as mud yet?

 

[daBear]

Perfectly clear, and thanks again.

Like Kenny said, one way to remember whether you need a PB sleeve or not is that only the last valve in the series circuit doesn't need one.
