Abstract: A diaphragm is provided that includes a tubular sidewall and a first elastomeric material. The tubular sidewall has an open end and an enclosed end and comprises fabric having a plurality of yarns disposed in a bias weave pattern. The first elastomeric material is disposed over the fabric at a predetermined thickness.

Abstract: An actuator assembly for use in conjunction with a pneumatic valve assembly of the type which includes an airway having an inlet port, an outlet port, and a valve disposed within the airway and configured to be moved between an open position and a closed position, comprises a first actuator coupled to the valve for moving the valve between the open position and the closed position in a first operational mode, and a second actuator coupled to the valve for opening the valve in a second operational mode.

Abstract: There is provided a method for repair of a regulator valve. The present invention provides a method for repairing a regulator valve. The method provides a machining of a housing so as to incorporate an oversize poppet. A poppet is provided that matches the resized housing. Further the poppet is shaped so as to provide an increased efficiency in the regulation of the air flow through the valve. Additionally the poppet is selected of a material that provides an increased wear life over the original material.

Abstract: A valve assembly includes a fully-integrated actuator assembly. The actuator assembly includes, within a single housing assembly, a torque source, a position sensor, a gear train, and an output shaft. The torque source is adapted to receive one or more position control signals and, in response, to supplies a drive force. The position sensor is coupled to receive the drive force and, in response, supplies a signal representative of valve position. The output shaft is coupled to receive the drive force from the torque source, and thereby selectively moves the valve, upon receipt of the drive force, between the open and closed positions.
