+86 15359408275ProAct Gen3 Flex Model III Actuator - Woodward ProAct Gen3 Flex Series
Woodward ProAct Gen3 Flex Model III 8404-329 is an electric rotary actuator used to position compatible turbine or engine control hardware. The official industrial turbine catalog identifies this exact order number as the Model III D+ configuration with a 4-20 mA command interface.
The actuator translates the analog control demand into controlled rotary output. Its mechanical installation, supply, command scaling, direction and travel limits must agree with the governor or turbine control application.
Woodward lists 8404-027, 8404-026 and 8404-114 as earlier part numbers associated with the 8404-329 entry. This relationship supports identification but does not remove the need to compare connectors, shaft hardware, linkage geometry and approved retrofit instructions.
Commission 8404-329 by proving minimum and maximum position, 4-20 mA calibration, direction of travel, feedback, loss-of-signal response and the complete shutdown path. Do not energize the actuator against an unverified mechanical stop.
