Good evening! “Recycling” a 7308 loader previously mounted on a TC29 tractor, had hydraulic hoses made to replace the hard lines from pump/diverter to the valve. I️ have those lines connected to the P, PB and T ports of the 2-spool valve. The work ports are labeled A1/A2, B1/B2. My dilemma in connecting to the loader lines is that, with joystick vertical, A1 and A2 are located horizontally left and right from each other at the top, and B1/B2 are horizontally opposed at the bottom of the valve. Should lines from one cylinder set still be connected to A1/A2 as a control set, or A1/B1 which are vertical to each other?

A1 and b1. I suspect the number correlates to the spool. And the letter the port. If not..just swap hoses.

You want the cylinder to be on the same spool. Thus it can open both ports. One port to pressurize and one to take fluid.
