Yes you can. Valves are chosen according to flow, so they can often be smaller than the pipe upstream or downstream of them, which are chosen to minimize pressure losses.

Why not use a 1" main line?

There might be a need to eliminate pressure losses in the main line, and bumping it up a size or two will accomplish that.

Totally understand friction loss. I was just assuming that someone who is asking a question like this is probably not building a system large enough to be concerned with it.

I'd stick to all 1" to save on parts/adaptors.

Never assume. Some folks have hundreds, if not thousands, of feet of pipe runs, or maybe a limited-pressure source that makes conservation of pressure the higher priority.
