Abstract
A modular air shut-off valve, particularly useful within the air conditioning environmental control system of an aircraft, is provided, which comprises a housing sized for insertion into a duct of the air conditioning system, a vane pivotally mounted within the housing for pivotal movement between open and closed positions and having flexible portions along its edges contacting the housing in the closed position for providing a resilient seal and to allow pressure relief in the event of overpressure within the duct.
