Robust structure, suitable for industrial and marine environments
Application Scenarios: Liquid fuel supply control for gas turbine power generation, mechanical drive, and marine propulsion systems. Compatible with diesel, JP series aviation fuel, kerosene, gasoline, and other internationally compliant distillate fuels.
Performance Parameters: Metering accuracy meets industrial gas turbine control requirements, with wide flow regulation range and fast response.
Material Composition: Valve body and internal wetted parts use corrosion-resistant alloy or stainless steel materials; sealing components use fluorocarbon rubber (FKM), suitable for various liquid fuel environments.
Structural Features: Standard Woodward liquid fuel valve structure with standardized interface for adaptation to various actuators, facilitating on-site installation and maintenance.
Working Principle: The valve is driven by an external actuator to adjust the valve opening, changing the fuel flow area to achieve fuel flow output proportional to the control system command. A built-in or external differential pressure regulating device maintains a constant differential pressure across the metering port, ensuring flow accuracy.
Installation Requirements:
-
Install in the gas turbine fuel supply main line
-
Valve body fixation requires compliant fasteners
-
Electrical wiring must be executed per the requirements of the matching actuator and control system
-
Reserve sufficient maintenance space for periodic inspection
Usage Precautions:
-
Fuel must be filtered to 20 microns or finer, with water content controlled within 0.1% by volume
-
Periodically inspect the tightness of electrical connections
-
Avoid long-term operation in environments exceeding the specified temperature range
-
Before maintenance, the fuel supply must be cut off and the system confirmed depressurized
