TG Actuator

Electro-Hydraulic Actuator for Steam Turbines

TG-13E & TG-17E Actuators

Woodward’s TG-13E/TG-17E self-contained electro-hydraulic actuators are used in the replacement of TG governors with an actuator and electric control system. The TG-13E and 17E proportional electro-hydraulic actuators convert an electrical signal to a corresponding proportional output shaft position in order to position the valve that controls the flow of steam (or energy medium) to the turbine. The actuators are intended for controlling small steam turbines that drive loads such as alternators, dc generator pumps, compressors, fans or papermaking machines.
