    Abstract: A check valve includes a valve body, a pair of stoppers, a hinge pin, and one or more flappers. The valve body includes an inlet end, an outlet end, and an inner surface that defines a flow passage between the inlet end and the outlet end. The inner surface further defines a valve seat adjacent the inlet end. The stoppers are integrally formed on the valve body inner surface, and each has a first end and a second end. The hinge pin is disposed within each hinge pin opening and extends across the flow passage. The flappers are disposed within the flow passage and are rotationally mounted on the hinge pin. Each of the one or more flappers is rotatable between a closed position, in which the flapper engages the valve seat, and a full-open position, in which the flapper engages the pair of stoppers.

    Abstract: Embodiments of a cabin outflow valve having one or more laterally-tapered sealing surfaces are provided, as are cabin pressure controls system including cabin outflow valves. In one embodiment, the cabin outflow valve includes a frame and a first door, which is pivotally coupled to the frame and which is rotated by an actuator between open and closed positions. The first door includes, in turn, a torque input point at which the actuator applies a closing force when rotating the first door into a closed position. A laterally-tapered sealing surface extends along a lateral axis of the cabin outflow valve and has a profile height decreasing with increasing proximity to the torque input point. The laterally-tapered sealing surface helps to ensure the formation of a complete lateral seal when in the first door is rotated into the closed position to significantly reduce or eliminate leakage through the cabin outflow valve.
