120E4 Series Integrated Metering Valve/Actuator, Cummins PT Fuel System
The ADB120E4 is a rotary-output, linear-torque, proportional, electric fuel metering servo for use on Cummins engines with PT fuel systems. Energized by signals from a speed control unit, this actuator is capable of delivering fuel at rates up to 1700 Ibs/hr.
Since the design is totally sealed, outstanding reliability is achieved. A single compression spring is used to improve reliability. No maintenance is required.
