WOODWARD 8404-2063: L-Series Integrated Throttle Body (ITB) (36mm, Sealed)
The Woodward 8404-2063 represents a configuration within Woodward’s L-Series that combines an electric actuator, an embedded controller, and an Integrated Throttle Body (ITB) into a single, compact package. It’s specifically tailored for position control or process control applications, offering precise management of air flow.
Product Overview
- Product Type: Integrated Electric Actuator, Position/Process Controller, and Throttle Body (ITB)
- Manufacturer: Woodward
- Series: L-Series
- Function: Primarily designed for position control (e.g., controlling throttle plate angle) or process control (e.g., air/fuel ratio management) by regulating air flow via the integrated throttle body.
- Throttle Body Size: Features a 36 mm diameter throttle body, suitable for specific engine sizes and airflow requirements.
- Design: Microprocessor-based control integrated directly into the electric actuator and throttle body assembly.
- Key Features: Sealed design, 12/24 VDC compatibility, and often comes with default parameters for simplified setup.
Detailed Description
The Woodward L-Series is renowned for its advanced and integrated engine control solutions. The 8404-2063 is a prime example, streamlining engine management by combining multiple critical functions into one durable unit:
- All-in-One Integration: This unit combines the electric actuator (the mechanical part that moves the throttle plate), the electronic controller (the “brain” that processes commands), and the throttle body (the mechanism that regulates air intake) into a single, compact assembly. This drastically simplifies installation, reduces wiring complexity, minimizes potential points of failure, and saves valuable space on the engine.
- Position or Process Control: Unlike dedicated speed controllers, this model is designed for precise position control of the throttle plate, or for process control where the throttle position is varied to achieve a desired outcome (like a specific air/fuel ratio). This makes it highly versatile for various engine types, especially those running on gaseous fuels.
- 36 mm Throttle Body: The 36 mm diameter indicates the flow capacity of the throttle body, making it suitable for engines that require this specific airflow range. It provides a larger airflow capacity compared to the 25mm or 30mm ITB options.
- Sealed Design: The “Sealed” characteristic means it’s built to withstand harsh engine environments, providing enhanced protection against moisture, dust, and vibration, which contributes to its long-term reliability.
- Microprocessor-Based Control: The embedded controller utilizes sophisticated algorithms to precisely manage the throttle plate’s position based on incoming command signals, ensuring accurate and responsive control.
- Versatile Power Input: Compatible with both 12 VDC and 24 VDC power systems, offering flexibility for different vehicle or industrial applications.
- Programmability and Default Parameters: Like other L-Series components, the 8404-2063 is highly configurable via Woodward’s PC-based service tool software. It often comes with “Default Parameters” pre-loaded, which can significantly simplify initial setup and commissioning.
Applications
The Woodward 8404-2063 is typically used in:
- Gaseous Engine Air/Fuel Ratio Control: Providing precise air/fuel mixture management for engines running on natural gas, LPG, or other gaseous fuels, optimizing combustion efficiency and reducing emissions.
- Engine Bench Testing: For applications requiring precise and repeatable control of airflow for engine development or testing.
- Industrial Pumps, Compressors, and Fans: Where engines drive these machines and require accurate air intake control for performance and efficiency.
- Generator Sets: For applications where precise load response and emissions control are critical.
- Other Mobile and Industrial Gas/Gasoline Engines: As a direct replacement for traditional throttle valves, offering integrated and advanced control.
