I believe that the spacer partially rides in the hole that the valve rides in, helping to keep the valve and shaft from deflecting. It acts like a bushing and a spacer.

Can it run without it? I guess so, but it would be more durable and precise with it.

The power valve works perfectly without any problems ,maybe in the future will buy this spacer .
