ML7420A/ML7425A,B
Electric Linear ValveActuator
GENERAL
TheML7420A / ML7425A,B actuators are formodulating
control with controls providing an analog output of
0 to 10Vdc or 2 to 10Vdc. They operateHoneywell’s standard
valves in heating, ventilation and air conditioning (HVAC)
applications. The direction of movement is reversible by
means of an internal selector plug.
