Most filters will have an arrow imprinted on them to show you the In/Out.

If you're talking about a valve, some valves will have a similar arrow. But some valves, depending on their design, don't have a specific input/output and can be installed either way.

Does this help? Or can you clarify your question?

Yes
I am installing a whole house filter. I need to tie into the main line inside the garage but I am unable to tell how the water flows. I need this information so I can cut the main and feed it into the in port of my filter.Name:  image.jpg

In most instances the lower entrance is the origin point, but you need to determine for sure what is on the other side of that wall. I don't think that ball valve is the only demarcation point for the water. There should be a 1" pipe with a PRV attached to it, reduced to a 3/4" pipe at some point. Point of interest.....why so many filters? Why not clear cups? You can't tell when they are dirty.
