Am I correct in saying the valve should always be open while there is air pressure?

That depends on which position you call "open" and "closed." It sounds like Cokomo calls "shut" the position when there's no pressure and you're breathing room air through the hole in the elbow.
The asphyxiation flap in both swivels, shuts and is audible when it does and exhalation is greatly reduced .

The pressure is not getting to throat and it seems I'm waking up due to apneas and finding it difficult to exhale.
