    ML6421, ML7421 405 lbf Non-Spring Return Globe Valve Actuators

    Discontinued

    ML6421 floating control and ML7421 modulating control 405 lbf Non-Spring Return Electric Linear Valve Actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications.

    Overview
    This product has been discontinued.
    Honeywell will provide product support until
    The ML6421A,B Non-Spring Return Electric Linear Valve Actuators are suitable for use with low-voltage, single-pole double-throw (spdt), Series 60 two-position and floating controllers. These actuators operate standard Honeywell valves in heating, ventilating, and air conditioning (HVAC) applications.The ML7421A,B Non-Spring Return Electric Linear Valve Actuators are modulating control actuators used with controls 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.
