History & Background (Dossier)

The general use of an Iris value is in various industrial applications as a control valve for chemicals, dairy, food, minerals, plastics and pharmaceuticals. Iris valves are often used to handle friable products because of their gentle closing action. Many companies utilize Iris valves as a means of shutting off material being discharged from bulk bags.

Iris valves are also used as a door mechanism on some kinds of controlled environment constructions, like a starship or orbital complex. Usually installed on a ladder access between levels, the iris valve allows closing the access point (important for preserving atmosphere in case of a breach) without the extra mounting of a door and in the confined space between floors.
