Woodward LQ Series Liquid Fuel Metering Valves

LQ Series Liquid Fuel Metering Valves LQ3, LQ25, LQ25T

LQ3
The LQ3 valve is suitable for use on gas turbines in the 1000 to 6000 kW output power range, depending on available fuel properties and conditions. There are two port sizes for the LQ3: the 0.033 in² (21.3 mm²) port is designed for maximum fuel flows of 1000 to 2000 lb/hr (454 to 907 kg/hr), and the 0.067 in² (43.2 mm²) port is designed for maximum fuel flows of 2000 to 4000 lb/hr (907 to 1814 kg/hr). The minimum metered flow of the LQ3 is 80 lb/hr (36 kg/hr). These flows assume a specific gravity of 0.77. All materials of the LQ3 are corrosion resistant.
The LQ3 utilizes the same bypassing differential pressure regulator that is currently used in Woodward's 1907 Small Liquid Fuel Valve series. This design has years of excellent operation history.

LQ25
The LQ25 valve is suitable for use on gas turbines in the 6000 to 42 000 kW output power range, depending on available fuel properties and conditions. There are three port sizes for the LQ25: the 0.1 in² (64.5 mm²) port is designed for maximum fuel flows of 4000 to 8000 lb/hr (1814 to 3629 kg/hr), the 0.2 in² (129.0 mm²) port is designed for maximum fuel flows of 8000 to 18 000 lb/hr (3629 to 8165 kg/hr), and the 0.3 in² (193.5 mm²) port is designed for maximum fuel flows of 18 000 to 26 000 lb/hr (8165 to 11794 kg/hr).
The minimum metered flow of the LQ25 is 80 lb/hr (36 kg/hr). These flows assume a specific gravity of 0.77. All materials of the LQ25 are corrosion resistant, or protected against corrosion.
