The 225 Series Electric Actuator is a rotary-output, linear-torque, proportional servo. This electromechanical actuator is typically used as an engine fuel control positioning device. An internal spring provides fail-safe operation by forcing the actuator to the fuel shutoff position when the actuator is de-energized.
The speed of operation of the actuator is typically faster than competitive units. This provides a more stable and rapid response to transient conditions. Applications include fuel injection pumps (with or without mechanical governors), rotary-type pumps, and medium-sized gaseous-fueled engines. The 25 degrees of rotation expands the application to a wider variety of engines.
