Woodward 9908-001
Product Name: Oil Metering Valve (9908 series)
Product Introduction: This model is listed among Woodward’s “Oil Metering Valve 9908-002, 9908-300, and similar” in the official Woodward Installation and Operation Manual, indicating it belongs to the same oil metering valve product family.
Technical Specifications: As a member of the 9908 series oil metering valve family, it shares the common platform architecture with related models. Specific detailed technical parameters for 9908-001 require reference to the official Woodward Oil Metering Valve Installation and Operation Manual (which covers 9908-002, 9908-300, and similar configurations).
Detailed content
Functional Features: Precision oil/fuel metering capability; compatible with Woodward hydraulic and electronic control systems; designed for industrial gas turbine fuel control applications.
Application Scenarios: Industrial gas turbine liquid fuel metering and control systems; works in conjunction with Woodward actuators and control systems.
Material Composition: Corrosion-resistant alloy and stainless steel construction consistent with Woodward liquid fuel valve standards; FKM sealing elements.
Structural Features: Based on the hydraulic liquid metering valve platform, the valve incorporates electrohydraulic servo valve assembly, trip relay valve assembly, hydraulic filter assembly, and DCDT position feedback sensor (as documented in the Hydraulic Liquid Metering Valve technical manuals).
Working Principle: The hydraulic liquid metering valve uses a dual coil electrohydraulic servo valve assembly to control the position of the metering valve plunger. A DCDT position feedback sensor provides position feedback to the control system. The bypass valve section senses fuel pressures to maintain regulated differential pressure across the metering port.
