Mixers are available for a wide variety of naturally aspirated and turbocharged engines. Woodward mixers provide high homogeneity at very low resistance. All mixers feature robust, simple construction with no moving parts, and can be easily combined with Woodward air/fuel ratio control systems.

The Flo-TechTM ITB integrated throttle body and actuator is designed for direct replacement of manual throttle bodies, and is designed with flow shaping to assist in engine idle stability. The throttle body will provide equivalent maximum flow rates of standard butterfly throttle bodies of the same diameter. The system contains a return spring to fully comply with DOT 571.124 specifications. Determination of the proper size requires a knowledge of the absolute pressure drops across the valve, the expected temperature of the gaseous media flowing, and the density of the gas. Cv (volume coefficients) are provided to determine the flow vs. angle. For initial testing, a valve body diameter similar to the one typically used on the application can be used. The Flo-Tech integrated actuator/throttle body requires no actuator or linkage.

The ProActTM ITB integrated throttle body and actuator complements the existing Woodward ITB family in larger bore sizes. The ProAct ITB includes 107 mm, 120 mm, and 135 mm bore sizes, and is designed for use with engines in the 1-2 MW range. The ProAct ITB is designed to couple directly to Woodward's ProAct actuators (electro-magnetic, 75 degree-of-travel devices), and therefore alleviate the problems associated with linkages on gas engines (such as setup, non-linearity, and wear.)
