The Woodward GS16 gas valve is designed for industrial gas turbine engines with maximum power ratings between 10 and 50 MW. Like the GS6, it combines a self-cleaning metering valve with a high-torque actuator and on-board electronic controller, delivering flow turn-down ratios exceeding 100:1 and positive shut-off exceeding ANSI B16.104 Class III requirements.
Key Features
Metering
- Spherical fuel metering element with precision-machined port
- Self-cleaning, shear-type metering action prevents deposit buildup
- Flow turn-down ratios exceeding 100:1
- Positive flow shut-off exceeding ANSI B16.104 Class III
- Single moving part: metering element, rotor, and resolver on one solid shaft
Actuation & Control
- On-board electronic controller module for simplified packaging
- Rare earth permanent magnets for high force in compact package
- Backlash-free design with virtually infinite positioning resolution
- High-precision resolver for valve position feedback
- Designed for 10–50 MW gas turbines
- Suitable for base and Dry Low Emission (DLE) configurations
Applications
- Industrial gas turbine fuel metering (10–50 MW)
- Power generation, compressor, and mechanical drive applications
- Base turbine configurations
- Multiple valve configurations for Dry Low Emission (DLE) turbines
