+86 15359408275505E Digital Governor for Extraction/Admission Steam Turbines · Woodward 505E Control Series
Woodward 9907-165 is the 180–264 Vac version of the 505E Digital Governor for steam turbines with controlled extraction and/or admission pressure. The exact part number and power option are identified in Woodward manual 85018V1.
Woodward 9907-165 coordinates turbine speed or load with extraction and admission pressure control for engineered generator or mechanical-drive applications. The application program must match the turbine valves, pressure transmitters, actuator directions and operating priorities.
The 505E platform provides configurable control, sequencing, protection interfaces, local operation and plant-system integration. Commissioning requires validated speed sensing, pressure signals, actuator outputs, permissives, trips, alarms and communication settings.
A replacement Woodward 9907-165 must retain the 180–264 Vac supply option and the approved 505E application configuration. Back up the settings and compare revision, terminal assignments, actuator ranges and extraction/admission logic before installation.

Woodward 9907-165 is the 180–264 Vac version of the 505E Digital Governor for steam turbines requiring controlled extraction and/or admission pressure together with speed or load control.
Woodward 9907-165 uses the HVAC option rated 180–264 Vac. Verify the supply, protective earth, disconnect, fuse, terminal plan and nameplate before applying power.
Woodward 9907-165 is configured for compatible extraction or admission steam turbines in generator or mechanical-drive service. Valve arrangement and pressure-control objectives must match the engineered application.
Woodward 9907-165 belongs to the 505E family and supports controlled extraction and/or admission pressure. A standard 505 controller is intended for turbines without that pressure-control requirement.
Verify Woodward 9907-165 speed inputs, pressure transmitters, actuator outputs, generator or process signals, permissives, trips, alarms and communication wiring against the approved turbine drawings and configuration.
Commission Woodward 9907-165 by validating sensing polarity, valve directions, actuator ranges, pressure and speed loops, sequencing, protection interfaces, trip tests and operating transitions before enabling automatic control.
No direct substitution should be assumed. The replacement must match Woodward 9907-165 power input, revision, terminals, approvals, firmware and complete extraction/admission application configuration.
Retain the Woodward 9907-165 program, service settings, calibration data, valve curves, pressure setpoints, communication parameters and trip-test records so the exact engineered behavior can be restored.
Provide the complete Woodward 9907-165 part number, revision, serial number, 180–264 Vac confirmation, turbine type, valve arrangement, extraction/admission requirements, configuration backup, approvals, quantity and destination.
Send the complete model, part number, revision, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
