Product Profile
The Woodward GS16 9908‑1501 functions as an electrically‑driven gas fuel metering valve built for industrial and aeroderivative gas turbine units. Equipped with integrated on‑board positioner electronics, this hardware bridges turbine control systems and fuel gas piping, delivering real‑time modulation of gas flow to stabilize combustion performance across variable load conditions. It serves as a critical final‑control element within gas turbine fuel skids for power generation and mechanical‑drive assets.
Core Mechanical & Electronic Highlights
One standout design feature is its shear‑style self‑cleaning metering mechanism. While running, the rotary spherical metering element scrapes away condensates, tar residues and particulate buildup, greatly lowering the risk of port blockage when handling impure field gas. Only one primary moving shaft carries the metering sphere, actuator rotor and resolver feedback assembly, cutting mechanical backlash and boosting positioning repeatability.
Built‑in resolver feedback continuously feeds actual valve position back to the on‑board driver, supporting closed‑loop positioning, fast response under 100 ms, and positive tight shut‑off upon emergency shutdown triggers. Rated for maximum gas inlet pressure up to 750 psig, the unit tolerates wide fuel and ambient temperature ranges for harsh plant environments.
Target Deployment Scenarios
This GS16 variant fits gas turbines ranging from 10 MW to 50 MW output capacity. Typical deployments include:
‑ Utility and captive power‑plant gas turbines running on natural gas, LNG or mixed hydrogen‑containing fuels
‑ Compressor‑station mechanical‑drive turbine packages
‑ Multi‑valve arrangements for dry‑low‑emission combustion systems
‑ Retrofit and spare‑part replacement for legacy Woodward turbine control setups
Operational Notes & Replacement Context
GS16 series has entered legacy status; original OEM new production will be discontinued in near‑term future, though overhaul and repair services remain available for existing fleets. When performing swap‑out, technicians must verify flange dimensions, voltage rating, resolver configuration and conduit entry type to match the existing turbine control cabinet wiring. Proper hazardous‑location certified plugs shall be fitted for any unused conduit openings in explosive‑classified plant areas.
Summary
Woodward GS16 9908‑1501 remains a widely‑used field‑proven fuel metering valve. Its self‑cleaning structure, integrated position control and high pressure capability make it a reliable spare component for maintaining uptime on aging industrial gas‑turbine installations across power and oil‑gas sectors.
