Page 7: Chapter 1. General Information
General The TM-100i/3171A gas valve is designed for metering gaseous fuel to industrial and marine gas turbine engines. The TM-100i actuator is used to drive the 3171A gas valve, closed loop to position demand. Valve position feedback is provided by a resolver directly coupled to the valve metering sleeve. Having the feedback on the valve prevents errors in the valve position due to windup in the actuator and valve linkage, and makes replacement of the actuator in the field possible. -

3171A Gas Valve and TM-100i Actuator Manual 40157 Fluid enters the actuator via a 40 µm nominal last-chance protective filter and passes to the torque motor servovalve which also has a filter for the fluid going to the torque motor’s jet pipe. -
Page 9: Chapter 2. Installation
Installation Unpacking Be careful when unpacking the TM-100 driver and TM-100i actuator/3171A gas valve. Check the devices for signs of damage such as a bent or dented case and loose or broken parts. If damage is found, notify the shipper immediately. The devices may be stored in their original shipping containers until they are ready for installation. -

Manual 40157 3171A Gas Valve and TM-100i Actuator Figure 2-2. Recommended Torque Pattern After the valve is installed in the piping system, the piping connections should be checked for any leaks. Use water, air, or inert gas to check. Remove the protective caps from the hydraulic supply and drain fittings. -

Page 24: Chapter 4. Actuator/Valve Calibration
Manual 40157 Chapter 4. Actuator/Valve Calibration The TM-100i actuator/3171A gas valve is typically used in applications that require extremely high accuracy, like dry low emissions (DLE) control. For that reason, all calibration of the actuator/valve assembly is performed at the factory. -
Page 25: Chapter 5. Troubleshooting
Since the calibration is between the valve and the resolver, it is possible to replace the actuator in the field without the loss of calibration. Failures of the resolver will most likely result in the unit having to be recalibrated at the factory. Consuls a qualified Woodward service facility for more information. Woodward... -
