Because an O-ring seal is dynamic, I don't think that's a worry.

So long as the preload is sufficient to form an initial seal when the valve closes, then the pressure differential will deform the O-ring to either complete the seal at pressure, or fail in extrusion.

Preload/initial_squeeze isn't what creates an O-ring seal. It just gets it started. Right?
