All of our hydraulic governors for turbines are from Woodward, the leading name in governors and related products. As a Woodward Authorized Independent Service Facility, we are qualified to provide onsite and on-call service for hydraulic governors.
We carry the following hydraulic governors for turbines:
Woodward TG611-13/-17 Governor
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.
Features include:
- API 611 Compliant
- Low cost
- Speed droop control
- Integral overspeed test device
- Weatherproof
- Self-contained sump
- NEMA “A” speed control
- 16 and 23.7 Nm (12 and 17.5 lb-ft) outputs
- Designed for harsh environments
Woodward TG611-13/-17 Governor
The PG Actuator converts a given electrical input signal from the turbine control and converts it to a proportional hydraulic output.
The PG Actuator is used to replace PGA/PGE-type governors, providing the advantages of electronic control with the convenience of the existing PG-type drive and linkage. An LVDT is available to provide voltage feedback proportional to fuel-rack position. We recommend the PG Actuator for installation involving unattended starts.
Features include:
- Proportional electric/hydraulic actuator
- Rotary or linear output
- Works with all Woodward 0–200 mA output electronic controls
- Self-contained oil supply
- Integral magnetic pickup and LVDT available
