APPLICATION
The 35 and 70 lb-in. (4 Nm and 8 Nm) 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.
