I replaced the sand in my sand filter and was surprised to find that, in the process, removing the multi-port was easy. Unusually easy. Basically, after I loosened the clamp, the valve basically lifted off like I was lifting a cup off the table.

Upon inspection, I discovered that the reason no effort was required was because the plastic is cleanly separated from the valve.

Turns out the plastic was well secured and tightly held in place on the lateral and took a little bit of prying to get it off. I don't think it was glued on to the lateral. It was just holding in place from inherent friction.

My thoughts were to just put it back in place and let the valve sit back in place. However, now that it's been removed once, the plastic piece does not hold in place. It freely drops down.

Is it possible (reasonable) to re-secure the plastic with glue and/or tape or do I have to get a brand new multi-port valve?

That's the diffuser for the valve to evenly distribute incoming water over the sand bed. It may or may not have ever been glued to the valve body, but there looks like some residue of adhesive on both the valve and that part. Others are just "clicked" on.
Plast-Aid would probably successfully reattach it to the valve body. Just a small amount around the perimeter of the diffuser and at the center should do it.
If the valve is old, you may want to go ahead and replace it, then you won't worry about other parts going bad.
