A relatively compact, lightweight outflow valve assembly includes suitable redundancy features that allow the valve assembly to meet regulatory requirements for certain postulated single point failures. The valve assembly includes a valve body that is constructed at least partially of a non-metallic material and has an outer surface and an inner surface that defines a flow passage having at least two flow ports. A sleeve is disposed within the valve body flow passage that is constructed at least partially of a metallic material. The sleeve has a flow passage formed therein that is in fluid communication with the valve body flow passage flow ports. A valve element is disposed within the sleeve flow passage and is moveable between at least an open position and a closed position. A plurality of brackets is mounted on the valve body outer surface and is coupled to the sleeve. When the valve assembly is installed in an aircraft, the plurality of brackets further couples the sleeve to the aircraft fuselage.

We claim: 1. A dual-wall flow passage assembly for a valve, the dual wall flow passage assembly comprising: a valve body constructed at least partially of a non-metallic material and having an outer surface and an inner surface, the valve body inner surface defining a flow passage having at least two flow ports; a sleeve disposed within the valve body flow passage, the sleeve constructed at least partially of a metallic material and having at a flow passage formed therein, the sleeve flow passage in fluid communication with the valve body flow passage flow ports; a plurality of brackets mounted on the valve body outer surface and coupled to the sleeve; and a plurality of ribs formed on the valve body inner surface and extending radially inwardly therefrom, each rib disposed at least proximate an outer surface of the sleeve; and a plurality of fasteners, each fastener coupled between one of the plurality of brackets and the sleeve and extending through the valve body and one of the plurality of ribs; wherein the ribs isolate the valve body from the sleeve and provide redundancy by preventing crack propagation from the valve body to the sleeve. 2. The dual-wall flow passage assembly of claim 1, wherein each fastener is a rivet. 3. The dual-wall flow passage assembly of claim 1, further comprising: a mount flange disposed proximate one of the valve body flow passage flow ports and extending radially outwardly from the valve body, the mount flange configured to mount the valve body to an aircraft bulkhead. 4. The dual-wall flow passage assembly of claim 3, wherein each of the plurality of brackets includes at least a first section and a second section, the first section mounted on the valve body outer surface, the second section disposed at least proximate the mount flange. 5. The dual-wall flow passage assembly of claim 3, wherein: one of the valve body flow passage flow ports has a first cross sectional flow area; and one of the valve body flow passage flow ports has a second cross sectional flow area that is greater than the first cross sectional flow area. 6. The dual-wall flow passage assembly of claim 1, further comprising: a sealing compound disposed between the sleeve and the valve housing inner surface. 7. The dual-wall flow passage assembly of claim 6, wherein the valve element comprises: a butterfly plate having an outer periphery; a reinforcing ring coupled to the butterfly plate; and a wiper seal disposed between the reinforcing ring and the butterfly plate, at least a portion of the wiper seal extending beyond the butterfly plate outer periphery. 8. The dual-wall flow passage assembly of claim 1, further comprising: a valve element disposed within the sleeve flow passage and moveable between at least an open position and a closed position; and a drive shaft coupled to the valve element and rotationally coupled to the valve housing, whereby rotation of the drive shaft moves the valve element between the open and closed positions. 9. The dual-wall flow passage assembly of claim 1, wherein the metallic material is aluminum. 10. The dual-wall flow passage assembly of claim 1, wherein the non-metallic material is a composite material. 11. The dual-wall flow passage assembly of claim 10, wherein the composite material is selected from the group consisting of fiber reinforced polyetheretherketon (PEEK), and fiber reinforced polyetherimide (PEI). 12. The dual-wall flow passage assembly of claim 1, wherein the valve body further includes an actuator mount surface formed thereon, the actuator mount surface configured to couple to a valve actuator. 13. An outflow valve assembly, comprising: a valve body constructed at least partially of a non-metallic material and having a valve body outer surface and a valve body inner surface, the valve body inner surface defining a flow passage having at least two flow ports; a sleeve disposed within the valve body flow passage, the sleeve constructed at least partially of a metallic material and having a flow passage formed therein, the sleeve having a sleeve outer surface, the sleeve flow passage in fluid communication with the valve body flow passage flow ports; a valve element disposed within the sleeve flow passage and moveable between at least an open position and a closed position; a plurality of brackets mounted on the valve body outer surface; a plurality of ribs formed on the valve body inner surface and extending radially inwardly therefrom, each rib disposed at least proximate the sleeve outer surface; and a plurality of fasteners, each fastener coupled between one of the plurality of brackets and the sleeve and extending through the valve body and one of the plurality of ribs. 14. The outflow valve assembly of claim 13, further comprising: a mount flange disposed proximate one of the valve body flow passage flow ports and extending radially outwardly from the valve body, the mount flange configured to mount the valve body to an aircraft bulkhead. 15. The outflow valve assembly of claim 14, wherein each of the plurality of brackets includes at least a first section and a second section, the first section mounted on the valve body outer surface, the second section disposed at least proximate the mount flange. 16. An outflow valve assembly comprising: a valve body constructed at least partially of a non-metallic material and having a valve body outer surface and a valve body inner surface, the valve body inner surface defining a flow passage having at least two flow ports; a sleeve disposed within the valve body flow passage, the sleeve constructed at least partially of a metallic material and having a flow passage formed therein, the sleeve having a sleeve outer surface, the sleeve flow passage in fluid communication with the valve body flow passage flow ports; a valve element disposed within the sleeve flow passage and moveable between at least an open position and a closed position; a plurality of brackets mounted on the valve body outer surface; a plurality of fasteners, each fastener coupled between one of the plurality of brackets and the sleeve and extending through the valve body; and a plurality of ribs formed on the valve body inner surface and extending radially inwardly therefrom, each rib disposed at least proximate an outer surface of the sleeve, wherein each fastener is coupled between one of the plurality of brackets and the sleeve and extends through the valve body and one of the plurality of ribs. 17. An outflow valve assembly, comprising: a valve body constructed at least partially of a non-metallic material and having an outer surface and an inner surface, the valve body inner surface defining a flow passage having at least two flow ports; a mount flange disposed proximate one of the valve body flow passage flow ports and extending radially outwardly from the valve body, the mount flange configured to mount the valve body to an aircraft bulkhead; a sleeve disposed within the valve body flow passage, the sleeve constructed at least partially of a metallic material and having at a flow passage formed therein, the sleeve flow passage in fluid communication with the valve body flow passage flow ports; a plurality of ribs formed on the valve body inner surface and extending radially inwardly therefrom, each rib disposed at least proximate an outer surface of the sleeve; a valve element disposed within the sleeve flow passage and moveable between at least an open position and a closed position; a plurality of brackets mounted on the valve body outer surface, each bracket including at least a first section and a second section, the first section mounted on the valve body outer surface, the second section disposed at least proximate the mount flange; and a plurality of fasteners, each fastener coupled between one of the plurality of brackets and the sleeve and extending through the valve body and one of the plurality of ribs.
