A fuel control unit (FCU) is a control system for gas turbine engines. ... (FADEC): A digital computer which controls a servo-operated fuel valve. In this case the ...
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

An HMU is still required because electrical actuators (torque motors or stepper motors) are needed to convert the digital signals from the FADEC into fuel flow changes. The HMU has to implement the following: the variable restriction (called the fuel metering valve FMV) and the pressure drop across it (by using a bypass valve between the high ...
The blue valve body is visible in-line with the pipe. The valve actuator opens or closes the butterfly disc of the valve based on electrical signals sent to the actuator. Another valve actuator is visible in the background, with windows to indicate the valve position. A valve actuator is the mechanism for opening and closing a valve. Manually ...
An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. [1] An actuator translates such an input signal into the required form of mechanical energy.
