ML6425, ML7425 Spring Return
Electric Linear Valve Actuators
APPLICATION
The ML6425 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 ML7425 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 heating,
ventilating, and air conditioning (HVAC) applications. An
internal selector plug can be used to reverse the direction of
action.
