The Woodward PROACT™ ITB (Integrated Throttle Body) is an advanced butterfly valve that combines an electric actuator and a throttle body into a single unit. This specific model, designated as an “MS” (Multi-Stage or a specific series) Speed Controller, features a 120mm bore and is a vital component for precisely controlling the flow of air or a pre-mixed air/fuel mixture to an engine to regulate its speed. It is a more advanced unit that can function as a standalone speed controller, eliminating the need for a separate governor.
PROACT ITB Speed Controller Applications and Features
The PROACT ITB is a key part of Woodward’s globally recognized portfolio of energy control solutions. This specific unit is engineered for durability and reliable performance in demanding applications:
- Integrated Speed Control: Unlike a standard throttle body, this unit integrates the speed governing function directly into the actuator. It receives a speed setpoint and precisely controls the throttle plate to maintain the desired engine speed, providing a complete solution in one package.
- Precise Control: The unit provides high-speed, bi-directional, and highly accurate positioning of the throttle plate, allowing for superior control of engine dynamics and performance.
- Robust Construction: Engineered to withstand high levels of vibration and temperature, the PROACT ITB is designed for a long service life in harsh industrial environments.
- Wide Application Range: The 120mm bore size and speed control functionality are suitable for use on large gas engines, typically in the 1–2 MW range, for applications such as power generation, compression, and mechanical drives.
