What is an IRIS Valve?

[BetterThanLife]

The rotating airlock is probably one of the safest ways to have an airlock. (You don't have to decide which side to open first.

) Though the mechanism would actually require more space than the IRIS valve. It might work for an Airlock, but it wouldn't fit on standard deckplans as a Bulkhead door. Which is how the majority of IRIS valves are employed.

Looking further an IRIS valve in a bulkhead, and one where crew and passengers routinely walk through, would have to be in the neighborhood of 2m tall and 1 meter wide. Andrew has it right in his "Traveller Trailer," but the issue is still where do the leaves go when the door is open? The normal allowed space for an IRIS valve is 1.5 meters wide by 3 meters tall, by (roughly) 10-20cm deep. The door pieces have to go somewhere.

Not sure how you get it to be more space than the Iris Valve, BTL, Measuring Andrew's drawing in the thread above, the doorway is only 50% of the total width, I reckon the rotating valve will give a 60% doorway.
Are you talking about the 'length' of corridor it takes up? Yes, it would be deeper, but if you have the corridor length available, there is nothing to stop these being fitted in bulkheads - apart from canon, of course. I was just looking at their technical merits rather than their tenacity to canon.

IMTU, I don't have bulkheads pierced by anything other than airlocks, from a safety perspective.
