TG611 Governors are API-611 compliant, self-contained, mechanical-hydraulic, speed-droop governors for use on small steam turbine driving pumps, compressors, or generators, where isochronous (constant speed) operation is not required. These governors are directly coupled to the steam-turbine’s rotor or auxiliary shaft to sense and control turbine speed.
These governors are designed for API-611-based turbine applications, and include a special Overspeed Test Device, allowing controlled and safe turbine overspeed trip testing.
