Detailed content

Technical Specifications:​ As a member of the 1907 valve family, it shares the core specification platform with other 8917-series configurations:
  • Fuel Types: Aviation gasoline, JP-4, JP-5, or diesel fuel
  • Specific Gravity: 0.70 to 0.85
  • Maximum Inlet Pressure: 950 psig (6550 kPa)
  • Maximum Outlet Pressure: 900 psig (6206 kPa)
  • Maximum CDP: 155 psig (1069 kPa)
  • Static Test Pressure: 1400 psig (9653 kPa)
Functional Features:​ Mechanical linkage operation driven by governor/actuator; precision-machined metering ports; optional LVDT position feedback; optional bypass relief configuration.
Application Scenarios:​ Industrial gas turbine liquid fuel metering for power generation, mechanical drive, and marine propulsion.
Material Composition:​ Valve body constructed in aluminum alloy or stainless steel; corrosion-resistant internal flow components; FKM sealing elements.
Structural Features:​ Consists of a fuel-metering valve section (hollow plunger within a ported sleeve), a bypass valve section (spring-loaded rolling diaphragm), with optional LVDT linear variable differential transformer for electronic position feedback.
Working Principle:​ The fuel valve is mechanically linked to and operated by a governor/actuator which determines the fuel flow requirement. The hollow plunger position within the ported sleeve determines the size and shape of the metering port. The bypass valve section senses both fuel inlet and outlet pressure via a spring-loaded rolling diaphragm to control bypass plunger position.
Installation Requirements:
  • Install the fuel valve square with the governor/actuator linkage to prevent binding
  • The actuator should use approximately two-thirds of the available output between minimum and maximum
  • Design the linkage to provide linear connection between the actuator and fuel valve
  • Unit is calibrated before shipment; minimize field adjustments
Usage Precautions:
  • Accommodate fuel filtration per Woodward specifications
  • Regular monitoring during turbine operation is mandatory
  • Check for excessive leakage when valve is closed; any leakage to the turbine indicates wear requiring immediate replacement and factory service
  • Follow all safety warnings regarding overspeed shutdown devices
