Woodward 9908-272
Product Name: GS6 Gas Fuel Metering Valve
Product Introduction: The 9908-272 is a GS6 gas fuel metering valve from Woodward. It is an electrically actuated control valve used on industrial and aeroderivative gas turbine engines that require gas fuel flows up to 15,000 lb/hr (6803 kg/hr). The assembly provides a reliable, cost-effective interface between electronic control systems and gas turbines used in electrical power generation, compressor, or mechanical drive applications.
Detailed content
Technical Specifications:
- Maximum Gas Supply Pressure: 750 psig (5170 kPa)
- Fuel Temperature: -40 to +200 °F (-40 to +93 °C)
- Ambient Temperature: -40 to +200 °F (-40 to +93 °C)
- Control Port Sizes: Available in 0.15, 0.30, 0.45, 0.60, 0.75 sq in
- Input Voltage: 24 VDC
Functional Features: The gas throttling section uses a self-cleaning, shear type of action that keeps the control port free of contamination. The valve is electrically actuated with an on-board driver. It can be used for base turbines or in a multiple valve configuration for low emissions requirements. Five control port sizes are available for optimized fuel flow.
Material Composition: The valve assembly combines a highly robust self-cleaning metering valve with a high-torque actuator.
Structural Features: The valve assembly features an on-board electronic controller module. It utilizes a single moving part for reliable performance. All-electric actuation.
Working Principle: The self-cleaning, shear-type metering action keeps the metering port free from performance-limiting deposits of gas condensates, contaminants, and system debris.
Installation Requirements: The valve assembly can be used for base turbines or in a multiple valve configuration for low emissions requirements.
Usage Precautions: Ensure the gas supply pressure does not exceed 750 psig. Operate within the specified fuel and ambient temperature ranges.
