Electro-Hydraulic Actuator for Steam Turbines
Woodward’s PGPL electro-hydraulic actuator replaces PGPL, PGL, and PGD type governors on steam turbines, providing the advantage of electronic control with the convenience of the existing PG-type drive and linkage.
The PGPL Actuator/Driver is an electro-hydraulic actuator with a proportional driver interface which can be used with electronic controls providing a 0 to 200 mA position signal. The actuator is designed for use with Woodward controls
