Woodward 9902-380

Product Name: VSV / IGV Servovalve and Actuator System Component
Product Introduction: The 9902-380 belongs to Woodward's VSV (Variable Stator Vane) and IGV (Inlet Guide Vane) electro-hydraulic control product family, covered by Woodward manual 40136. As a member of the 9902 VSV/IGV series, 9902-380 functions within the dual servovalve and actuator system architecture that provides closed-loop positioning of compressor variable geometry on gas turbines.

Woodward 9902-222

Product Name: 3055 VSV Servovalve
Product Introduction: The 9902-222 is the 3055 VSV (Variable Stator Vane) Servovalve, documented in Woodward manual 40124. It is a torque-motor-driven two-stage servovalve designed for hydraulic control of VSV actuators on gas turbines. It converts an electrical command signal from the turbine control system into a precisely metered hydraulic flow to position the VSV actuator, preventing compressor stall and optimizing part-load efficiency.

Woodward 9908-023

Product Name: LQ25 Series Liquid Fuel Metering Valve (Oil Metering Valve, 9908 family)
Product Introduction: The 9908-023 is a member of the Woodward LQ25 liquid fuel metering valve family. Like the 9908-011, it utilizes an integrated brushless DC electric actuator and rotary plate valve body design, delivering precise fuel metering for gas turbines in the 1000 kW to 42 000 kW range. It is configured as a standard LQ25 variant within the 9908 part-number series.

Woodward 9908-011

Product Introduction: The 9908-011 belongs to Woodward's LQ25 family of all-electric liquid fuel metering valves designed for industrial and aero-derivative gas turbine engines. The valve integrates a rotary plate metering port, a brushless DC torque motor actuator, and a non-contacting position sensor into a single compact body. It provides a reliable, cost-effective interface between electronic engine control systems and gas turbines used in power generation, mechanical drive, and marine applications.
