Third Function Valve Port ID help

[pripyat]

Can someone verify that I have identified these ports correctly? Seen in the diagram are the only indicators on the valves themselves (P,T) and (P,C,T).



[edit]
Bottom thumb valve is Prince MB11B5C1
Top FEL valve is Mahindra stock BESKO 8625-300-500-5

Looks right assuming you have the power beyond plug in the thumb valve.

Just to verify - there is a hose that goes to the back of the tractor, pictured below.



Is that power beyond from the FEL valve or tank?

That looks like it controls the 3 point. It doesn’t look like a return line. That line should go to the pump. Are you saying that goes back to your loader control?

Likely, but you not provided much detail. Does your FEL valve have labels next to the ports.

These are the only ID marks on the valve:





The hose that I was asking about that goes to the rear is in the top right port right above the "T" of the FEL valve. Every letter designator listed on the valve is on my diagram. A little ambiguous..

I'm new at this, but other than ports going to cylinders (hydraulic lines Ax & Bx) I believe 'P' is from pump (or proceeding valve assembly) where you are getting hydraulic pressure, 'T' is to tank (return to tank from valve) and 'PB' (power beyond) is to next valve's 'P', downstream from valve in question.....

If I'm wrong just shoot me....

The inlet (from pump) will be on the same side as the pressure relief. The PB and return line will be on the other side.....typically.

This should help- different brand same layout.

The port on the side near your "P" is the input pressure port.

On the picture with the "T", the "T" port is on the left. The power beyond on the right, its the one that sticks out more and has that extra fitting attached between the elbow and the monoblock valve. That extra fitting is the power beyond plug that converts the valve from a standard open center valve into a power beyond valve. This is the place you add extra valves downstream of your FEL.

Would the "plug" also be alternative "T" port?
