WOODWARD 9907-165 Front panel mounted second generation user configurable steam turbine digital governor for extraction and intake control with 220 Vac power input rated Class 1, Class 2 standard position. Upgrade now to the next generation plug-in replacement 505XT.
The steam turbine digital governor is a device used to control the speed of the steam turbine. It usually consists of sensors, controllers and actuators that adjust the fuel or steam flow in real time to keep the steam turbine speed within a set value range.1

Among them, the WOODWARD 9907-165 sensor is used to monitor the speed and load of the steam turbine, the controller receives the sensor signal and calculates the corresponding control signal according to the set value, and the actuator adjusts the fuel or steam flow to the steam turbine according to the control signal.

In addition, the WOODWARD 9907-165 digital governor also has a variety of functions and features. For example, some advanced digital governors can provide automatic start sequence for hot start and cold start, with temperature input options, critical speed avoidance, external alarm and trip input, etc. 2. At the same time, the digital governor usually has a high-precision adjustment ability, which can quickly and accurately respond to changes in speed or load to ensure the stable operation of the steam turbine.
