Woodward TG-17 9904-802 is an ATEX-compliant mechanical-hydraulic turbine governor configured for a rated speed of 2400 rpm. The TG mechanism senses drive speed and positions its terminal output to regulate the turbine energy input.
Woodward Manual 04042 lists 17.5 ft-lb work output and counterclockwise drive rotation when viewed from the top. The documented speed-setting arrangement is a speed-setting screw, so the linkage and adjustment method must match the installed turbine package.
The published configuration table identifies 2900 rpm high speed at 2 degrees, 1800 rpm rated speed at 38 degrees, 2010 rpm rated speed at 2 degrees and 1200 rpm low speed at 2 degrees. These values identify the factory configuration and are not field setpoints for a different TG-17 suffix.
Before installing 9904-802, verify the ATEX marking, governor drive, rotation, mounting, oil supply, terminal-shaft travel and trip interface. Commission speed response and stability under the approved turbine procedure.
