Woodward GS16 Gas Fuel Metering Valve

Features and Benefits

Valve assembly features an on-board electronic controller module for ease of system packaging and installation

Self-cleaning, shear-type metering action keeps the metering port free from

performance-limiting deposits of gas condensates, contaminants, and system debris

Utilizes a single moving part with a fuel-metering element, actuator rotor,

and position feedback resolver mounted on a single solid-piece shaft

Port Sizes

The GS16 is available with three different standard port sizes to optimize valve performance

for various flow and pressure drop requirements within a gas turbine. Standard port geometric areas are:

GS16:

• 1.00 in2 (645.1 mm2)

• 1.50 in2 (968.0 mm2)

• 2.00 in2 (1290.3 mm2)

GS16DR – Standard Valve Design:

• 1.00 in2 (645.1 mm2)

• 2.00 in2 (1290.3 mm2)

GS16DR – High Pressure Valve Design:

• 1.00 in2 (645.1 mm2)

The standard metering ports are contoured to provide approximate square law relationships between commanded position and effective area.
