Embodiments of a lightweight, high temperature airborne valve are provided. In one embodiment, the airborne vale includes a valve element and a flowbody. The flowbody is formed at least partially from a titanium aluminide alloy and has a flow passage therethrough in which the valve element is movably mounted. Embodiments of a method for producing such a lightweight, high temperature airborne valve are also provided. In one embodiment, the method includes the steps of forming a lightweight flowbody at least partially from a titanium aluminide alloy, hot isostatically pressing the lightweight flowbody, and machining the lightweight flowbody to desired dimensions.

1. A lightweight, high temperature airborne valve, comprising: a valve element; anda flowbody having a flow passage therethrough in which the valve element is movably mounted, the flowbody formed substantially entirely from a near-stoichiometric titanium aluminide alloy having a density between approximately 3.5 grams per cubic centimeter and approximately 5.0 grams per cubic centimeter, the near-stoichiometric titanium aluminide alloy comprising, by atomic percentage: about 50.2% titanium;about 45.0% aluminum;about 2.0% manganese;about 2.0% niobium; andabout 0.8% titanium diboride. 2. A lightweight, high temperature airborne valve according to claim 1 further comprising an oxidation-resistant coating applied over at least one surface of the flowbody. 3. A lightweight, high temperature airborne valve according to claim 1 further comprising a wear-resistant coating applied over an inner surface of the flowbody contacted by the valve element in a closed position. 4. A lightweight, high temperature airborne valve, comprising: a valve element; anda flowbody having a flow passage therethrough in which the valve element is movably mounted, the flowbody formed substantially entirely from a near-stoichiometric titanium aluminide alloy having a density between approximately 3.5 grams per cubic centimeter and approximately 5.0 grams per cubic centimeter, the near-stoichiometric titanium aluminide alloy comprising, by atomic percentage: about 51.4% titanium;about 43.5% aluminum;about 4.0% niobium;about 0.1% boron; andabout 1.0% molybdenum. 5. A pneumatic avionic system for deployment aboard an aircraft, the pneumatic avionic system comprising: an aircraft duct; anda lightweight, high temperature airborne valve fluidly coupled to the aircraft duct, the lightweight, high temperature airborne valve comprising: a flowbody having a flow passage therethrough; anda valve element movably mounted within the flow passage for modulating fluid flow therethrough;wherein the flowbody is formed substantially entirely from a titanium aluminide alloy having a density between approximately 3.5 grams per cubic centimeter and approximately 5.0 grams per cubic centimeter, the titanium aluminide alloy selected from the group consisting of a first titanium aluminide alloy and a second titanium aluminide alloy;wherein the first titanium aluminide alloy comprises: about 50.2% titanium;about 45.0% aluminum;about 2.0% manganese;about 2.0% niobium; andabout 0.8% titanium diboride; andwherein the second titanium aluminide alloy comprises: about 51.4% titanium;about 43.5% aluminum;about 4.0% niobium;about 0.1% boron; andabout 1.0% molybdenum. 6. A pneumatic avionic system according to claim 5 wherein the flowbody is formed substantially entirely from a near-stoichiometric titanium aluminide alloy. 7. A pneumatic avionic system according to claim 5 further comprising an oxidation-resistant coating applied over at least one surface of the flowbody. 8. A pneumatic avionic system according to claim 5 further comprising a wear-resistant coating applied over an inner surface of the flowbody contacted by the valve element in a closed position.
