VALVCON ESR Series Electric Actuators
The Valvcon ESR Series electric actuator provides an internal bank of super-capacitor power storage devices that never need replacement. It’s designed for two-position operation providing true two-wire control: When the actuator is energized it drives to one position; when de-energized the actuator powers itself to the other position. The Valvcon ESR-Series is appropriate for applications that require operation from a single pair of wires.
