    Linear Actuators

    ML6425, ML7425 135 lbf Spring Return Globe Valve Actuators

    ML6425 floating control and ML7425 modulating control 135 lbf Spring Return Electric Linear Valve Actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications.

    Overview

    The ML6425 Spring Return Electric Linear Valve Actuators are floating control actuators used with controllers that provide a switched or floating single-pole double-throw (spdt) output. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications.

    The ML7425 Spring Return Electric Linear Valve Actuators are modulating control actuators used with controllers that provide an analog output of 0 to 10 Vdc or 2 to 10 Vdc. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications. An internal selector can be used to reverse the direction of action.

    Features & Benefits:
    • Quick and easy installation, no separate linkage required.
    • True spring return on power failure, ML6425A and ML7425A drive valve stem down, ML6425B and ML7425B draw valve stem up.
    • Conduit connector is standard.
    • No adjustments required.
    • Low power consumption.
    • 135 lbf for high close-off ratings.
    • Force-limiting end switches.
    • Synchronous motor.
    • Maintenance free, corrosion resistant design.
    • Position Feedback signal on ML7425
    • Fail-safe position selection for control signal loss on ML7425
    Certifications:
    • Underwriter’s Laboratories, Inc. UL94-5V Flame Retardant.
    • Meets CE requirements
