Abstract

An outflow valve is provided for use in conjunction with an actuator. In one embodiment, the outflow valve includes a frame and a first door rotatably coupled to the frame. The outflow valve is configured to be moved by the actuator between an open position and a closed position. The first door includes: (i) a main body having a sealing edge, and (ii) a J-shaped bellmouth fixedly coupled to the main body proximate the sealing edge. The J-shaped bellmouth is configured to condition fluid flow through the outflow valve when the first door is in the open position.
