Abstract: A low friction control servo is provided that includes a housing having an inlet and an outlet. A flexible valve plate is disposed within the housing and includes a curved arm. The curved arm is adapted to flex between (i) an closed position wherein airflow through the outlet is substantially impeded, and (ii) an open position. An actuator is coupled to the housing and engages the curved arm to control the position thereof.

Abstract: A plug valve assembly includes a plug and a segment seal assembly. The segment seal assembly is configured to reduce the differential pressure load across the segment seal assembly when the valve is closed. The segment seal includes an opening in fluid communication with a sealed vent region that is formed between the segment seal and the plug.

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.
