Basic Principle Of Modulating Electric Actuators The proportional positioning is set by the input signal, say 0-10V where 0V is closed and 10V is open, 5V is 50% open. The positioner constantly monitors and compares the input control signal proportionately with the physical position of the output drive. Modulating control valves are devices used to regulate the flow of fluids, such as water, air, or steam. An electronic or mechanical actuator controls these valves. This actuator receives a signal from a control system and adjusts the valve's position to maintain a desired flow rate.
