The ML6421AB Non
Spring Return Electric Linear Valve Actuators are suitable for use with lowvoltage singlepole doublethrow (spdt) Series 60 twoposition and floating controllers. These actuators operate standard Honeywell valves in heating ventilating and air conditioning (HVAC)applications. The ML7421AB Non
Spring Return Electric Linear Valve Actuators are modulating control actuators used with control 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.
