There are a lot of terms used here and it can be confusing to some of us....myself included.
Like the term "piston valve" yes the valve uses a piston of some sort; but is it a barrel seal or chamber seal?
What exactly is a coaxal?
Some may not know what a QEV is...
Now I know that this is no easy task.... but I think it will simplify discussion and inspire new ideas....there are so many valve types that they need distinction and their own identity.
I made a piston valve is like saying I modded a sprinkler valve! WOW you modded a sprinkler valve.... was it a jar top or conventional top (they require different modd procedures)..... was it an in-line sprinkler or anti-siphon sprinkler...... or one of those weird ones that go IN a pipe?
And when you have a problem with "said" valve we will be able to diagnous it faster. It just makes sence to narrow our vast topics of our simple hobby......
