The Woodward LQ6 liquid fuel valve provides the flow range, accuracy, and response characteristics required for controlling industrial gas turbines in the 3 MW to 15 MW power range. By integrating Woodward’s proprietary electric actuation technology with a proven fuel-metering concept and on-board driver electronics, the LQ6 delivers exceptional performance in a compact, cost-effective package.
Key Features
Metering
- Rotary plate metering element with precision-machined port
- Self-cleaning, shear-type action prevents contaminant buildup
- Flow turn-down ratios exceeding 100:1
- Single moving part: valve plate, actuator rotor, and resolver on one shaft
- Integrated bypassing-type pressure regulator holds constant differential across metering port
- Requires positive displacement high-pressure fuel pump upstream
Actuation & Control
- On-board driver electronics simplify system design
- 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
- Reduces installation space, time, and cost
- Designed for 3–15 MW gas turbines
Applications
- Industrial gas turbine liquid fuel metering (3–15 MW)
- Power generation applications
- Mechanical drive applications
- Systems with positive displacement fuel pumps
