Turbine Fuel Valve Repairs

Steam valves, gas valves, and liquid fuel valves need routine maintenance to ensure turbine reliability, availability, and safe operation.

Woodward Gas Turbine Fuel Valve Maintenance Schedule

As recommended by Woodward, an overhaul of the component should be completed when the unit reaches either the Operating Hours or Years in Service interval, whichever comes first. Recommendations are based on normal operating conditions, fuel quality, past maintenance and environment.

Overhauling to Woodward’s factory standards will return the unit to “like-new” condition and allow for another full operating cycle before maintenance is required. Overhauled unit is returned with standard new part warranty of 18 months.

Woodward Steam Turbine & Engine Governor/Actuator Maintenance

• Change governor/actuator oil between 3,000 and 5,000 running hours
• Ensure the use of proper oil
• Perform overhaul and calibration between 20,000 and 25,000 running hours
• Repair of auxiliary equipment is also recommended

Catastrophic failure may result if governors are pushed past recommended limits of maintenance, i.e. seizure of oil pump, bearing failures, etc. If prime mover is critical to operations, a recommended preventive maintenance schedule should be followed. Repair costs can be excessive when units are operated beyond the hours of recommended maintenance.
