Don’t understand a few words in the book?

I need to check whether the valve is set for FLOW-UP, FLOW-DOWN, or TRIM? STANDARD TRIM? ANTICAVITATION TRIM?. Could you please help? !
In control valves, TRIM refers to the valve spool: standard trim for ordinary spools, and anticavitation trim for spools designed to prevent surge phenomena; these are usually implemented in multi-stage form to eliminate surge.
TRIM: Fine-tuning delimiter； STANDARD Standard (type) ； ANTICAVITATION: Cavity formation.
Is the flow direction one of flowing away or stopping? A literal translation would seem to be flowing upward, flowing downward!
FLOW UP: Low inlet, high outlet FLOW DOWN: High inlet, low outlet TRIM: Valve spool STANDARD TRIM: Standard valve spool, ordinary spool ANTICAVITATION TRIM: Anti-cavitation valve spool FYR.
I really found it very instructive; they wouldn’t allow me to post it even though I hadn’t reached the required word count. It was indeed educational
