I would like to ask for some advice regarding if and when getting a ratioed spool is needed.
We plan to use the Bosch Rexroth 4WRLE 25 valve (as we have these on the shelf) with a 150id cylinder and 100od rod. Would it be essential to get the valve adapted with the equivalent spool ratio?
This machine will only operate for a few weeks so it would be nice to keep the valves generic for future projects.
The rig is with the rod pointing up lifting a load.
What would the effect of having a 1:1 ratio spool give me vs a ratio spool on the control and motion?
Thanks in advance for everyones input.
