- Product Name: TG611-13 API611 Mechanical-Hydraulic Steam Turbine Governor
- Product Description: A self-contained mechanical-hydraulic speed droop governor designed specifically for API611-compliant steam turbines driving pumps, compressors, or generators where isochronous operation is not required. It controls turbine speed by sensing rotor speed via the input drive shaft and adjusting the turbine inlet steam valve position.
