Has anyone figured out a way to implement a valve mechanism for trumpets? I've tried so many different methods and nothing seems to work like it should.
Thanks!

I haven't actually made a trumpet so there's a good chance my advice won't help much, but some possible ideas are:

1. 3D printed valves; if you happen to have access to a 3D printer you can probably find designs online like this one:
https://www.thingiverse.com/thing:662115 or something similar. I believe most designs consist of many parts, so you might be able to find a way to just print the valves and have it work with what you have already. They might be finicky, however.

2. This is a rather underdeveloped idea, but maybe you can find a way to create something more like a rotary valve like this: Image
This might be more difficult to make, but there might be some way to use different PVC valves to change the path of the air, although I'm not sure how the sound quality of it would be.

3. If you really can't figure out the valves, it might be easier to make something more along the lines of a trombone with a slide rather than valves. You could also do something altogether different like making mouthpieces or interchangeable pieces of tubing of different lengths. It might be more practical to abandon a trumpet and choose something that would be easier to build/tune.

I'm not sure if this will help, so hopefully someone with more experience with building something like a trumpet has something more insightful to say, but that's just my two cents.

I'm not sure about this but it looks like they're using f=v/4L not f=v/2L. This doesn't entirely make sense, though, since a pan flute should be open on both ends, so I might be missing something.

Pan flutes are closed pipes....

Oh okay, that's what I was missing

It's sort of like a piano where instead of strings the hammers strike metal keys.
