The ProAct™ ITB integrated actuator and throttle body is designed to throttle air or air/fuel for gaseous engines. With bore sizes ranging from 85mm to 180mm, ProAct ITBs are designed for use with engines in the 1 MW to 2 MW range. The electromagnetic actuator has 75 degrees of travel, which alleviates the problems associated with linkages on gas engines (such as setup, non-linearity, and wear).
