Abstract: 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.

Abstract: Servo valve modules and torque motor assemblies are provided. In an embodiment, a servo valve module includes a housing assembly, a diaphragm, a valve assembly, and a spiral washer. The housing assembly includes two chambers, a valve port, an intake port, and an outlet flow channel. The diaphragm extends across one chamber to divide the chamber into a pressure reception section and a pressure transmission section. The valve assembly includes a valve seat adjacent to the valve port in the other chamber, a valve element to seat and unseat against the valve seat, and a valve plate in the pressure transmission section including a valve stem extend axially and disposed in the valve port to contact the valve element. The spiral washer is coupled to the valve element and extends across the chamber to provide a preload against the valve element to bias the element toward the closed position.
