Detailed content

  • Valve series: Woodward 1907
  • Manufacturer: Woodward (distributed under GE part numbering)
Functional Features:
  • Precision gas fuel metering capability for turbine control from start to full load
  • Compact and robust structure suitable for high-vibration environments
  • Standardized interface for integration with TM-series and EM-series actuators
Application Scenarios:
  • Small and medium-sized industrial gas turbine generator sets
  • Combined heat and power (CHP) and distributed energy systems
  • Gas engine fuel management systems
  • Marine and offshore gas power units
Material Composition:
  • Valve body: Precision-cast aluminum alloy or stainless steel
  • Metering spool: Surface-hardened wear-resistant alloy steel, precision ground
  • Seals: Gas-resistant fluorocarbon rubber (FKM) composite material
Structural Characteristics:
  • Precision metering port with a defined flow-to-lift relationship
  • Standard flange or threaded connection ports for pipeline integration
  • Smooth internal flow passages to reduce turbulence, noise, and pressure loss
Working Principle:​ Gas enters the valve through the inlet port and passes through the precision metering port to the turbine combustion system. The valve lift is driven by an external actuator, changing the gas flow area to achieve proportional fuel flow output according to the control system command.
Installation Requirements:
  • Install the actuator strictly in accordance with the corresponding Woodward manual
  • Ensure gas filtration at 25 μm absolute accuracy upstream of the valve
  • Verify coaxial alignment between the actuator and valve body
Usage Notes:
  • The valve must be operated within its specified mechanical and electrical limits
  • Unauthorized modifications constitute misuse and void warranty coverage
  • Read and observe the handling precautions for electronic controls to prevent electrostatic discharge damage
