Functional Features: Shear-type self-cleaning metering principle for strong anti-fuel-contamination capability. Integrated brushless DC actuator eliminates gear backlash for high positioning repeatability. Remote electronic driver unit enables closed-loop valve position control and fault diagnostics. Standard 4–20 mA interface compatible with various control systems. Factory-calibrated, no field calibration required.
Materials & Construction: Corrosion-resistant materials for all fuel-wetted components.
Applications: Widely used in gas turbine power generation, mechanical drive, and marine propulsion liquid fuel supply systems. Compatible with diesel, JP series aviation fuel, kerosene, gasoline, and international standard distillate fuels.
Installation & Notes: No field calibration needed — factory flow calibration is completed before shipment. Install per Woodward LQ25 series documentation.
