Woodward’s R-11, R-30, and R-120 electric actuators provide high torque rotary travel to precisely position various types of control valves and other mechanisms that operate in hightemperature, high-vibration locations. In reciprocating engine applications, these valves may include: fuel throttles, wastegates, exhaust gas recirculation (EGR), compressor recirculation (bypass), waste heat recovery (WHR), and exhaust. Additional applications on
reciprocating engines include variable turbine geometry (VTG) turbocharger actuation.
