The Woodward Electric Liquid Metering Valve (ELMV) controls liquid fuel flow rate to the combustion stages of industrial gas turbines. Its unique design integrates the valve, actuator, and throttling regulator into a compact, cost-effective assembly that directly meters flow with high accuracy independent of pressure drop across the valve.
Key Features
Design
- Integrated valve, actuator, and throttling regulator in one assembly
- Highly accurate flow-versus-stroke characteristic
- Flow metering independent of pressure drop across valve
- Integral throttling regulator maintains nearly constant delta-P across metering plug
- Compact, cost-effective package
Control
- Electric actuation for precise positioning
- Regulator characteristics can be added to control system for extreme accuracy compensation
- Designed for multi-stage combustion systems
- Compatible with industrial gas turbine fuel control architectures
Applications
- Industrial gas turbine liquid fuel metering
- Multi-stage combustion system fuel control
- Applications requiring high flow accuracy independent of pressure drop
