    Linear Actuators

    ML6420, ML7420 135 lbf Non-Spring Return Globe Valve Actuators

    ML6420 floating control and ML7420 modulating control 135 lbf Non-Spring Return Electric Linear Valve Actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications.

    Overview

    The ML6420 Non-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 ML7420 Non-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 HVAC applications. An internal selector plug can be used to reverse the direction of action.

    Features & Benefits:
    • Quick and easy installation, no separate linkage required.
    • Conduit connector is standard.
    • No adjustments required.
    • Low power consumption.
    • 135 lbf stem force for high close-off ratings.
    • Force-limiting end switches.
    • Manual operator.
