Technical Specifications:
  • Valve configuration: Small gas valve, valve body only
  • Valve series: Woodward 1907
  • Manufacturer: Woodward
Functional Features:
  • Fast, dynamic, and high-accuracy response meeting typical OEM specifications
  • Robust self-cleaning metering valve to reduce unplanned outages and support wellhead gas applications
  • 100% hydrogen models available for emissions reduction
  • Compliance with many international standards
  • All-electric integrated valve actuator design option for easier integration
Application Scenarios:
  • Aeroderivative gas turbines with single or multiple combustion manifold systems
  • Industrial gas turbine fuel metering
  • Wellhead gas applications
  • Hydrogen fuel applications
Material Composition:
  • Valve body: Aviation-grade aluminum alloy or precision-cast stainless steel
  • Metering spool: Surface-hardened wear-resistant alloy steel
  • Seals: Fluorocarbon rubber (FKM) composite material
Structural Characteristics:
  • Precision metering port; flow rate is a defined function of valve lift
  • Standard flange or threaded connection ports
  • Self-cleaning metering valve structure
  • Anti-vibration validated for aeroderivative gas turbine environments
Working Principle:​ Gas enters through the inlet port, passes through the precision metering port, and flows to the turbine combustion system. The valve lift is driven by an external actuator.
Installation Requirements:
  • Integrate with compatible Woodward actuators per manual
  • Upstream gas filtration: 25 μm absolute accuracy
  • Environmental temperature range: -20°C to +80°C
Usage Notes:
  • Operate within specified mechanical and electrical limits; unauthorized modification voids certification and warranty
  • Observe ESD handling precautions for electronic controls
  • Install overspeed shutdown devices independent of the control system for safety
