ProAct ITB Actuator

The ProAct Integrated Throttle Bodies (ProAct ITBs) are butterfly valves electrically actuated by ProAct actuator s to control flow output. With bore sizes ranging from 85 mm to 180 mm, these ProAct ITBs are designed for use with engines in the 1 MW to 2 MW range. This is an electromagnetic actuator with 75 degrees of travel, which alleviates the problems associated with linkages on gas engines (such as setup, non-linearity, and wear).
This direct combination of throttle and ac tuator results in excellent stability and transient characteristics, and requires no hydraulics, pneumatics, or governor gear train. Therefore, you end up with an efficient, long lasting, and easily-installed throttle option.
