Valtra active spool valve flow control

Hi looking at valtra actives can anyone tell me how you can control the oil flow on the manual spool valves

I have a T174 active with 4 spools. It's an annoying feature of the spools that they are all different. If you have two spools there is no adjustment. Spool one is 100% flow with a "motor" detent on the lift only, spool 2 is from memory 20% flow with no detent. Spool 3 where fitted has detent and flow both adjustable externally. Spool 4 where fitted has external detent adjustment and in cab flow adjustment although it can be hard to make small adjustments as it is a cable control.

Why they don't fit spools 1 and 2 with the same type of block as spool 3 I have know idea.
