Non-spring return direct coupled actuators

APPLICATION

The 35 and 70 lb-in. Non-Spring Return Direct Coupled
Actuators (DCA) are control actuators that provide floating or
proportioning control for valves and dampers. The
proportioning actuators accept a current or voltage signal from
a controller to position the damper or valve at any chosen
point between fully open and fully closed. Floating actuators
are suitable for use with single pole double throw (spdt)
floating thermostats or two-position control systems.
Two-position control requires installation of the 201052B
Auxiliary Switch.
