WHY didn't you get valve with two or three spools in one block??? OR, a "modular" valve, where you buy the exact sections you need, then bolt them together with "through bolts", finishing it off with a LH and a RH end section. Also, you are not understanding how the "power beyond" function works with valves for an open-center system. It is more complicated then you think. There are extra ports in the valves and extra internal passages and "lands and grooves" in the actual "spool" in the valve. That's why those valves are more expensive. If correctly set up, using valves designed to be set up like that, you will STILL have full flow available to the first spool. The power beyond port will connect to the next valve in the series, where the "power beyond" flow will be blocked UNLESS that spool is moved from center. So, if the first spool lifts the loader, you will have full flow there, UNTIL you move the second spool from center, say, for bucket tilt. ONLY THEN will the flow be split, and, yes, the lifting of the loader will slow down BUT ONLY WHILE THE BUCKET TILT IS ACTUALLY IN USE.
