VX200 Pro Valve Diagram?

[Jax]

I have the XS Scuba VX200 Pro Valve with the safety handwheel - two of them, actually. One of the handwheels has become harder to turn. I cannot find anything wrong by an external inspection, and would like to get an 'exploded view' diagram before I take it apart. I find nothing online nor does my LDS have anything.

How might I obtain a diagram of one of these handwheels?

Hey, thanks!

I just can't find anything on the green and red insides of the safety wheel . . . Hate to have it fall apart on me, and can't get it back together.

Jax,

Apparently, there are no schematics available for the handwheel. But Mark says that it shouldn't fall apart on you.

Super! Now if I can only determine why it's binding . . . .
