Non-Spring Return
Electric Linear Valve Actuators
APPLICATION
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.
