SQM5... actuators are uniquely suited for both industrial and commercial
applications. The high level of accuracy permits precise modulating control of
industrial process and process heating applications, often significantly enhancing
performance and product quality.
In commercial and industrial burner applications requiring high turndown and
reliable ignition, the auxiliary switches can be applied to create separate positions
for burner ignition and low fire. In dual fuel applications, additional switches can be
used to create separate high fire, low fire and ignition positions for each fuel. The
economy position switch is used to drive the actuator to the full closed position
when the burner is off.
In all applications, commissioning is simplified. Shaft and cam drum disengagement
clutches allow for the quick manual alignment of the actuator shaft and switch
cams. The forward/reverse toggle switch in combination with the auto/manual
selector switch provides direct manual control.
