The Woodward GS6 gas fuel metering valve is designed for high-performance fuel control on industrial gas turbines. It combines a robust self-cleaning metering valve with a high-torque electric actuator and on-board driver electronics, delivering flow turn-down ratios exceeding 100:1 with virtually infinite positioning resolution. Available in single or multiple valve configurations for base and Dry Low Emission turbines.
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: ANSI B16.104 Class II (0.15 in) / Class III (0.30–0.75 in)
- Single moving part: metering element, rotor, and resolver on one solid shaft
Actuation & Control
- On-board electric actuator driver for simplified packaging
- Rare earth permanent magnets for high force in compact package
- Backlash-free design with virtually infinite positioning resolution
- Single or dual redundant position feedback resolvers
- Dual signal conditioning with resolver fault detection (dual models)
- Selectable failure management options
Applications
- Industrial gas turbine fuel metering
- Power generation, compressor, and mechanical drive applications
- Single-manifold base turbines
- Multiple valve configurations for Dry Low Emission (DLE) turbines
