    The VALVCON ESR-Series electric actuator provides an internal bank of super-capacitor power storage devices that never need replacement. Designed for two-position operation, it provides 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.

    VALVCON™
    ESR-Series electronic spring-return electric actuator

    Electronic spring-return drives to fail position upon loss of power

    The VALVCON ESR-Series electric actuator provides an internal bank of super-capacitor power storage devices that never need replacement. Designed for two-position operation, it provides 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.

    Features

    • Compact and lightweight
    • Internal energy storage provides power to “safe” position during power outages
    • Field-settable to “fail-clockwise” or “fail-counterclockwise”
    • High standard duty cycle
    • True “two-wire”operation
    • Internal capacitors are rated for a minimum of 100,000 cycles

    Common use cases

    • Two-wire applications
    • On/Off service
    • Fail “safe” applications

    Applicable industries

    • Water/Wastewater
    • HVAC
