Delphi Smart Remote Actuators (SRAs) are electromechanical devices that actuate engine features, such as variable geometry (VG) and dual stage turbochargers, exhaust gas recirculation (EGR) valves and exhaust flap control valves. They also supply precise rotary position feedback to the engine control unit, which is provided by a controlled area network (CAN-protocol).
High vibration and temperature resistance capabilities enable Delphi SRAs to withstand harsh environments. Liquid cooling is also available for extremely high temperature environment applications to protect the brushless motor and the integrated electronics.

Delphi Smart Remote Actuators are typically used for high-demand EGR and turbo (vane, nozzle, waste gate and by-pass) applications, such as medium duty and heavy duty diesel engines to help provide optimum performance and enable compliance with current and future exhaust emissions standards.
Their durability, flexible mounting options and adaptability make Delphi Smart Remote Actuators ideal for the actuation of high-temperature gas controls and other powertrain devices.
